1.51	07-Jul-2025	rillig	jemalloc, stdio: skip lint warning 207 It has been disabled a few minutes ago and will be removed in a few minutes.
1.50	09-Dec-2024	maya	PR lib/58850: add man page link for snprintf_ss
1.49	20-Jan-2024	christos	branches: 1.49.2; Catch up with all the lint warnings since exit on warning was disabled. Disable 'missing header declaration' and 'nested extern' warnings for now.
1.48	04-Apr-2023	christos	PR/57250: Martin Husemann: dtoa mishandles infinite doubles on 32bit big endian machines. When long double support was added, the old code was kept for the regular double code. This code was never used because WIDE_DOUBLE was always defined in the Makefile. Remove that old code, and conditionalize the WIDE_DOUBLE code based on if long doubles are different than doubles on the specific platform.
1.47	29-Dec-2015	christos	branches: 1.47.18; 1.47.26; Add printf/scanf man pages from FreeBSD
1.46	13-Oct-2014	christos	PR/49279: Justin Cormack: add open_memstream
1.45	18-Jun-2014	christos	more man pages links
1.44	18-Jun-2014	christos	add mkostemp, mkostemps, mkstemps from FreeBSD.
1.43	16-Jan-2014	christos	branches: 1.43.2; "soon" is "now". Remove all __indr_reference crap.
1.42	19-Apr-2013	joerg	Add explicit locale versions for the printf family. Replace asprintf, snprintf and sprintf with simple wrappers around the corresponding va_list functions to reduce code duplication.
1.41	27-Mar-2012	christos	branches: 1.41.2; - widen the internal read and write calls to match the syscalls - add funopen2() which provides access to flush() and the wider calls. - make use of the new flush call in fmemopen()
1.40	22-Dec-2010	christos	branches: 1.40.6; document vsnprintf_ss
1.39	24-Sep-2010	christos	add man page as promised.
1.38	24-Sep-2010	tnozaki	add fmemopen(3) derrived from POSIX:2008. libc minor bump.
1.37	06-Sep-2010	christos	add dprintf and vdprintf
1.36	13-Jul-2009	roy	Add implementations for getdelim(3) and getline(3).
1.35	03-Feb-2007	christos	enable wide doubles.
1.34	27-Oct-2006	christos	branches: 1.34.2; Add signal-safe versions of snprintf and vsnprintf
1.33	16-Feb-2006	christos	- s/notyet/WIDE_DOUBLE/ - Add a little more glue for WIDE_DOUBLE; not done yet. - s/def FLOATING_POINT/ndef NO_FLOATING_POINT/ to reduce diffs with FreeBSD. - fix memory leak where each double formatted leaked 24 by calling __freedtoa() appropriately. the new gdtoa keeps a list of memory chunks allocated by malloc(), and it must maintained properly by calling __freedtoa() on the results of __dtoa() Hi Klaus! - in vfwprintf() make cvt return char * and convert it using __mbsconv(), instead of having it return wchar_t *. This should fix the memory leaks people have been reporting (eg. in top etc.)
1.32	28-Jul-2005	christos	PR/30845: Luke Mewburn: strerror_r(3) missing - Merge 4.4BSD strerror.3 man page changes that summarize information for all the error printing functions. This makes the perror(3) page obsolete. - Implement all error functions in terms of strerror_r(), including __strerror() which is not used internally. Can it be removed? - Bump version for strerror_r
1.31	12-Jun-2005	lukem	vfwprintf.c and vfwscanf.c now compile with -Wuninitialized
1.30	01-Jun-2005	lukem	Compile the following files with -Wno-uninitialized: vfprintf.c See rev 1.46 for why we can't fix this. vfwprintf.c Needs some effort vfwscanf.c Needs some effort
1.29	14-May-2005	christos	Add the missing wide char support functions from freebsd. XXX: long double support is missing until we get gdtoa, and add the necessary wide functions.
1.28	10-May-2004	drochner	remove the fgetstr manpage
1.27	09-May-2004	kleink	We now need an internal name for fileno(), since when buildling libc _REENTRANT we can no longer use the macro version from <stdio.h>.
1.26	21-Apr-2004	christos	Add a generalized version of fgetln that can stop at an arbitrary delimiter, and implement fgetln on top of that.
1.25	07-Mar-2003	tshiozak	branches: 1.25.2; add fgetws() and fputws() (lib/20576). Note: fgetws.c, fgetws.3, fputws.c and fputws.3 are obtained from FreeBSD, and fitted by sigsegv@infoseek.jp and me.
1.24	28-Jan-2003	kleink	Add a manual page for flockfile(3) etc.; while here, also add *_unlocked() to stdio(3) overview documentation. Fixes PR lib/20096 from Jason Thorpe.
1.23	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.22	30-Nov-2002	lukem	- Migrate fparseln(3) from libutil to libc, where it should have been in the first place... - Bump libutil major (to 7.0) and libc minor (to 12.91).
1.21	07-Dec-2001	yamt	- make FILE structure extensible without breaking binary-compatibility. - add fputwc, fgetwc, fwide and related functions. - add hooks needed to maintain the orientation of file stream.
1.20	25-Apr-2001	kleink	Document getc_unlocked(3), getchar_unlocked(3), putc_unlocked(3) and putchar_unlocked(3); fixes PR lib/11340.
1.19	08-Jul-2000	kleink	branches: 1.19.2; XCU5: Add fseeko() and ftello() functions which provide the functionality of fseek() and ftell(), respectively, but operate on file offsets of type off_t.
1.18	30-Aug-1998	perry	make sure asprintf and vasprintf get MLINKS to printf.3
1.17	28-Aug-1998	perry	add asprintf and vasprintf, originally written by Todd Miller for OpenBSD
1.16	27-Jul-1998	mycroft	Document mkdtemp(3).
1.15	27-Jul-1998	mycroft	Actually, FreeBSD calls this mkdtemp(). No point in creating a new name.
1.14	27-Jul-1998	mycroft	Add a mktempdir(), like mkstemp(), but it creates a directory.
1.13	27-Jul-1998	mycroft	If AUDIT, do not compile certain functions.
1.12	22-Oct-1997	lukem	- use CPPFLAGS instead of CFLAGS - use ${COMPILE.C} ... instead of ${CC} ${CFLAGS} -c ...
1.11	02-Apr-1997	kleink	branches: 1.11.2; RCSid police
1.10	25-Feb-1995	cgd	mktemp.c belongs here, not gen/Makefile.inc
1.9	02-Feb-1995	jtc	revert
1.7	22-Dec-1994	cgd	specify man pages the new way.
1.6	19-Sep-1994	mycroft	Move FLOATING_POINT definition into Makefile.inc.
1.5	04-Jan-1994	cgd	rename fgetline() and sharpen axe for bostic...
1.4	18-Oct-1993	cgd	don't compiler strerror.c source here, and clean up.
1.3	07-Oct-1993	jtc	Moved strerror.[c3] from libc/stdio to libc/string. Since perror is not permitted to change strerror()'s static buffer, I have changed both functions to pass their own buffers to the new library-internal function _strerror() that actually does the error message string look up. Split strerror manpage into strerror and perror manpages.
1.2	01-Aug-1993	mycroft	Add RCS identifiers.

Fix for issue reported in PR lib/35401 as well as related overflow bugs. deal with hex doubles. Instead of abusing stdio to get a signal-safe version of sprintf, provide one. remove __SAFE add long double and hex double support from freebsd. make this compile. add new prototypes. add the new files to the build. Note I am not bumping libc now, because these are not used yet. Merge the int bit with the high fraction bit. Add constants/macros needed by gdtoa. add constants used by gdtoa since the int bit is merged, do the explicit math. ext_int bit is no more. ext_int bit is no more. - merge change from freebsd - add support for building as vfprintf.c - XXX: we strdup to simplify the freeing logic. This should be fixed for efficiency in the vfprintf case. use vfwprintf.c enable wide doubles. some int -> size_t deal with sparc64 that has 112 bits of mantissa. make extended precision gdtoa friendly. int/size_t changes make this gdtoa friendly. remove dup definition use dtoa() instead of returning empty when we don't have extended precision information. Fix previous, add forgotten pointer dereference in the call to dtoa(). Add a cheesy workaround marked XXX for the situation where the strtod() implementation available in the environment does not handle hex floats. Discussed with and suggested by christos From Christos: gdtoa fixes for m68k. M68k ports should build now, but printing extended precision is a little off. vax does not have <machine/ieee.h> or long double It would be nice if the compiler provided something like __IEEE_MATH__ bring in FreeBSD's vfscanf() to gain multi-byte/collation support. Unfortunately it is too difficult to make vfwscanf and this share the same code like I did with printf, because for string parsing the code is too different.

1.17	25-Oct-2009	dsl	Lint is differentially far too picky... Remove some warnings that only appear on i386 (not on amd64) and that for some reason best known to others are deemed fatal for i386. Making this code 'pass lint' does absolutely nothing for its readability (etc).
1.16	24-Oct-2009	dsl	Remove a load of pointless casts - one that even lint doesn't bleat about.
1.15	26-Jan-2007	cbiere	* Consider all negative return values as error, not just -1. * Corrected cast because (size_t) (INT_MAX + 1) is bogus.
1.14	09-Feb-2005	kleink	A little libc namespace housekeeping exercise: * Make vfprintf_unlocked() an internal function, c.f. __svfscanf_unlocked(). * Add internal names for arc4random(), endnetpath(), fhstatvfs(), fstatvfs(), mkstemp(), shquote(), statvfs(), taddr2uaddr(), uaddr2taddr(), uuid_create_nil(), uuid_is_nil(), and wcwidth(). * Include namespace.h where supposed to.

1.11	26-May-2002	wiz	__STDC__ is always defined on NetBSD.
1.10	07-Dec-2001	yamt	- make FILE structure extensible without breaking binary-compatibility. - add fputwc, fgetwc, fwide and related functions. - add hooks needed to maintain the orientation of file stream.
1.9	24-Sep-2001	wiz	va_{start,end} audit: Make sure that each va_start has one and only one matching va_end, especially in error cases. If the va_list is used multiple times, do multiple va_starts/va_ends. If a function gets va_list as argument, don't let it use va_end (since it's the callers responsibility). Improved by comments from enami and christos -- thanks! Heimdal/krb4/KAME changes already fed back, rest to follow. Inspired by, but not not based on, OpenBSD.
1.8	13-Apr-2001	kleink	Need an internal name for asprintf(3).

1.7.6.4	02-May-2002	nathanw	Call the _unlocked versions of vfprintf() and __svfscanf(); there's no point in locking and unlocking a FILE object that only exists in the local scope. This also has the nice side effect of making sprintf() usable for debugging threaded code.

1.24	22-Jul-2021	christos	revert changes to fflush.c (1.18) and fvwrite.c (1.25) until we investigate collateral damage. Breaks h_intr.c test. Requested by RVP.
1.23	09-Jul-2021	christos	Don't adjust the buffers when write returns 0. This happens with fmemopen and other synthetic write functions. This fixes the unit-tests for fmemopen, but adjusting should be the right behavior for all cases?
1.22	08-Jul-2021	christos	Include the 0 return from write. Although the real write system call does not return 0, the synthetic writes from funopen/fmemopen could. This avoids infinite loops in >= test19 in fmemopen, but the tests still fail, perhaps because they assume the previous behavior, where flush does not adjust the stdio pointers on error.
1.21	08-Jul-2021	christos	Obey EINTR and return immediately adjusting for unwritten. From RVP
1.20	06-Jul-2021	christos	Handle EINTR, from RVP.

1.16	02-Dec-2009	roy	Reinstate __getdelim which does no locking. Callers are now required to FLOCKFILE so they can operate on fp as well.
1.15	24-Sep-2009	roy	__getdelim works on strings up to SIZE_MAX - 2 and returns 0 on EOF. getdelim works on strings up to SSIZE_MAX and returns -1 on EOF. __fgetstr is now just a wrapper around __getdelim and ensures that the buffer doesn't overflow the one provided by FILE. __slbexpand is now static in fgetwln as it is the only consumer of that func.
1.14	10-May-2004	drochner	After discussion with christos, turn fgetstr() into an internal function. Its API in inherently non-threadsafe (and it depends on certain properties of the underlying stdio implementation), so it shouldn't be a first-class function for general use, polluting the application namespace. Also remove the FLOCKFILE() code from it - this is under control of the calling function now. (XXX I'm not sure whether the FLOCKFILE() should be kept in fgetln(), this function cannot be used in multiple threads anyway. It doesn't hurt much, and it might prevent corruption of internal FILE structures.)
1.13	21-Apr-2004	christos	Add a generalized version of fgetln that can stop at an arbitrary delimiter, and implement fgetln on top of that.

Disable cancellation around the cond_wait() call, since that's also a cancellation point. Arguably, that would be better handled with pthread_cleanup_*(), but stubbing those for libc is difficult, and the current non-exception-based implementation of cleanup handlers is probably no faster than disabling and reenabling cancellation. Finally, it only happens in the slow path where the thread is going to sleep anyway...
1.7	21-Jul-2003	nathanw	Set the _LOCKINTERNAL() count on initial locking as well as subsequent recursive locks.
1.6	19-Jul-2003	nathanw	Use threadlib stub rather than pthread_setcancelstate() directly.
1.5	18-Jul-2003	nathanw	Move guts of flockfile()/funlockfile() to __flockfile_internal(), which takes an additional argument indicating whether this is an internal caller taking the lock or an external (application) caller. When making an internal lock, save the current thread cancellation state and disable cancellation until the matching unlock. This should prevent canccelled threads from exiting inside of stdio while holding a file lock and potentially leaving other parts of the FILE structure in an inconsistent state.
1.4	01-Feb-2003	nathanw	Revert the conversion to libpthread's recursive mutexes. Too much trouble is caused by the memory allocation in the mutex initialization, and uncontested mutexes and condition variables have become faster in the meantime.

The original changes were added in order to facilitate a usage of sanitizers against programs linked with NetBSD's libc. It is no longer needed, so abandon these changes. Sponsored by <The NetBSD Foundation>
1.18	05-Jan-2018	kamil	Include namespace.h in a few of libc source files The NetBSD Standard C Library uses internally some of its functions with a mangled symbol name, usually "_symbol". The internal functions shall not use the global (public) symbols. This change finishes elimination of usage of the global name of the following symbols: - close -> _close - execve -> _execve - fcntl -> _fcntl - setcontext -> _setcontext - wait6 -> _wait6 - write -> _write - writev -> _writev Sponsored by <The NetBSD Foundation>
1.17	09-Nov-2017	christos	Add O_REGULAR to enforce opening of only regular files (like we have O_DIRECTORY for directories). This is better than open(, O_NONBLOCK), fstat()+S_ISREG() because opening devices can have side effects.
1.16	04-Nov-2017	kre	Avoid losing a fd (ie: close it) in the (ever so likely) case that the fd exceeds the limits of what can be stored in a FILE (65535).
1.15	15-Mar-2012	christos	branches: 1.15.24; - ansify, knf. - no functional changes
1.14	22-Jan-2012	christos	From tnozaki@: make fpos_t a complex object that keeps track of the parse state of the stream. Change argument of the seek function to funopen() from fpos_t to off_t. Make f{g,s}etpos() use the new fpos_t struct, while providing backwards compatible entry points. Approved by releng@
1.13	13-Mar-2008	christos	branches: 1.13.6; Since _file is a short, check that the fd fits in it, otherwise bail with EMFILE. We treat _file as an unsigned short to double our range, with a special case for -1 (closed). Make a note of what we should do about stdio if we ever bump libc. We could change _file in the future compatibly to an int by putting it in the extension space but for now we don't bother.
1.12	07-Aug-2003	agc	branches: 1.12.22; 1.12.28; Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22280, verified by myself.

1.8	20-Sep-1999	lukem	back out the #ifdef _DIAGNOSTIC argument checks; too many people complained. _DIAGASSERT() is still retained.
1.7	16-Sep-1999	lukem	* use _DIAGASSERT() to check pointer arguments against NULL and file descriptors against -1 (as appropriate). * add actual checks which to detect stuff that would trigger_DIAGASSERT(), and attempt to return a sane error condition. * knf some code * remove some `register' decls. the first two items result in the addition of code similar to the following in various functions: _DIAGASSERT(path != NULL) #ifdef _DIAGNOSTIC if (path == NULL) { errno = EFAULT; return (-1); } #endif
1.6	03-Feb-1998	perry	remove obsolete register declarations

1.8	05-Jan-2009	tnozaki	1. reworking PR lib/40317: libnbcompat already contains empty fparseln.lo so previous fix doesn't work correctly. i've just added broken fparseln check to configure script. 2. reworking cross build breakage under FreeBSD/MacOS X. FreeBSD/MacOS X still have public /usr/include/runetype.h derived from 4.4BSD-Lite. so i renamed out private header from src/lib/libc/locale/runetype.h to src/lib/libc/locale/runetype_local.h to solve this problems. 3. fix build breakage when CITRUS=no was set.

FreeBSD/MacOS X still have public /usr/include/runetype.h derived from 4.4BSD-Lite. so i renamed out private header from src/lib/libc/locale/runetype.h to src/lib/libc/locale/runetype_local.h to solve this problems. 3. fix build breakage when CITRUS=no was set.

1.23	22-Feb-2020	kamil	Avoid undefined behavior in fread(3) On the first call to fread(3), just after fopen(3) the internal buffers are empty. This means that _r and _p (among others) are zeroed. Passing NULL to the 2nd argument of memcpy(3) for the zero length is undefined. Calling _p += 0 triggers LLVM UBSan (NULL pointer arithmetic). Calling _p += 0, p += 0 and resid -= 0 has no effect. Replace the "fp->_r = 0;" logic with a short circuit jump to __srefill() that sets _r internally and refills the FILE buffers. No functional change from an end user point of view, except skipping a few dummy operations on the first call, for a FILE pointer, to fread(3).

1.12	17-Sep-1999	lukem	revert previous; if we examine SUS more closely we find that unless explictly specified, use of a NULL pointer is undefined

Add constants/macros needed by gdtoa. add constants used by gdtoa since the int bit is merged, do the explicit math. ext_int bit is no more. ext_int bit is no more. - merge change from freebsd - add support for building as vfprintf.c - XXX: we strdup to simplify the freeing logic. This should be fixed for efficiency in the vfprintf case. use vfwprintf.c enable wide doubles. some int -> size_t deal with sparc64 that has 112 bits of mantissa. make extended precision gdtoa friendly. int/size_t changes make this gdtoa friendly. remove dup definition use dtoa() instead of returning empty when we don't have extended precision information. Fix previous, add forgotten pointer dereference in the call to dtoa(). Add a cheesy workaround marked XXX for the situation where the strtod() implementation available in the environment does not handle hex floats. Discussed with and suggested by christos From Christos: gdtoa fixes for m68k. M68k ports should build now, but printing extended precision is a little off. vax does not have <machine/ieee.h> or long double It would be nice if the compiler provided something like __IEEE_MATH__ bring in FreeBSD's vfscanf() to gain multi-byte/collation support. Unfortunately it is too difficult to make vfwscanf and this share the same code like I did with printf, because for string parsing the code is too different.

1.1.1.1	21-Mar-1993	cgd	initial import of 386bsd-0.1 sources
1.9.56.1	17-Apr-2012	yamt	sync with head
1.15	03-Jul-2017	wiz	Remove workaround for ancient HTML generation code.
1.14	16-Sep-2014	wiz	Remove trailing whitespace.
1.13	16-Sep-2014	apb	Rephrase the NOTE about embedded NUL characters, using "apparent length" for what strlen(3) reports, and "true length" for what the return value reports.
1.12	15-Sep-2014	christos	mention what happens if the line contains NUL's.
1.11	15-Sep-2014	christos	fix markup.
1.10	15-Sep-2014	christos	Fix documentation to reflect what happens when EOF is found before delimiter, aligning us with POSIX.
1.9	20-Apr-2011	enami	- Put empty line after the local variable definition in the sample code to improve readability. - Remove indirection operator to clarify error condition.
1.8	30-Jun-2010	jruoho	Use .Fn instead of .Fa for functions. Also rearrange slightly.
1.7	09-Dec-2009	joerg	Fix markup.
1.6	01-Dec-2009	wiz	Make HTML-ready, use standard section headers, fix Xr.
1.5	30-Nov-2009	roy	Note that callers should use feof(3) or ferror(3) to distinguish between EOF or an error.
1.4	30-Nov-2009	roy	Note that EOF returns -1 when no characters are read. Add code example.
1.3	25-Aug-2009	wiz	Note some restrictions for getdelim arguments noted by joerg. Bump date.
1.2	13-Jul-2009	wiz	The character is NUL, the pointer is NULL. Fix a typo. It's \-1, not -1. Add "and getline" in a few places. Add comma in enumeration. No dot needed in SEE ALSO. End sentence with a dot.
1.1	13-Jul-2009	roy	Add implementations for getdelim(3) and getline(3).
1.14	08-Jun-2017	uwe	Don't use "NULL" to talk about null-terminated strings. The C standard seems to be inconsistent about dash vs. space. Old text uses dash, Annex K uses space. I'll let wizd(8) to sort that out.
1.13	22-Jul-2011	joerg	Set error indicator on invalid arguments. From Carsten Hey.
1.12	07-Dec-2009	roy	Test against SSIZE_MAX as pointed out by enami tsugutomo.
1.11	02-Dec-2009	roy	Pass lint.
1.10	02-Dec-2009	roy	Reinstate __getdelim which does no locking. Callers are now required to FLOCKFILE so they can operate on fp as well.
1.9	01-Dec-2009	roy	Protect getdelim when used internally.
1.8	01-Dec-2009	roy	Remove __getdelim and just use getdelim. fgetstr now works with strings up to SSIZE_MAX as a result, but may reallocate buffers needlessly just like it used to when the buffer size exceeds INT_MAX. fgetstr converts errno EOVERFLOW to EINVAL on getdelim error.
1.7	25-Oct-2009	christos	revert some of dsl's changes to make things build on i386; he can undo what he wants when he comes back.
1.6	25-Oct-2009	dsl	Lint is differentially far too picky... Remove some warnings that only appear on i386 (not on amd64) and that for some reason best known to others are deemed fatal for i386. Making this code 'pass lint' does absolutely nothing for its readability (etc).
1.5	24-Oct-2009	dsl	Remove a load of pointless casts - one that even lint doesn't bleat about.
1.4	24-Sep-2009	roy	__getdelim works on strings up to SIZE_MAX - 2 and returns 0 on EOF. getdelim works on strings up to SSIZE_MAX and returns -1 on EOF. __fgetstr is now just a wrapper around __getdelim and ensures that the buffer doesn't overflow the one provided by FILE. __slbexpand is now static in fgetwln as it is the only consumer of that func.
1.3	14-Jul-2009	roy	Allow a buffer of SSIZE_MAX + 1 as the returned bytes do not include the NULL.
1.2	14-Jul-2009	christos	pass lint
1.1	13-Jul-2009	roy	Add implementations for getdelim(3) and getline(3).
1.3	02-Dec-2009	roy	Protect getline.
1.2	01-Dec-2009	roy	Protect getdelim when used internally.
1.1	13-Jul-2009	roy	Add implementations for getdelim(3) and getline(3).
1.18	04-Oct-2013	christos	avoid linker warning for compat symbols that are used internally in libc, by introducing a hidden compat_foo() function, using that internally in libc, and exposing foo as a strong alias to compat_foo(). I am open for better ideas.
1.17	15-Mar-2012	christos	branches: 1.17.2; - ansify, knf. - no functional changes

1.15	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22280, verified by myself.
1.14	18-Jul-2003	nathanw	#include "local.h" to get __flockfile_internal() prototype.
1.13	20-Sep-1999	lukem	back out the #ifdef _DIAGNOSTIC argument checks; too many people complained. _DIAGASSERT() is still retained.
1.12	16-Sep-1999	lukem	* use _DIAGASSERT() to check pointer arguments against NULL and file descriptors against -1 (as appropriate). * add actual checks which to detect stuff that would trigger_DIAGASSERT(), and attempt to return a sane error condition. * knf some code * remove some `register' decls. the first two items result in the addition of code similar to the following in various functions: _DIAGASSERT(path != NULL) #ifdef _DIAGNOSTIC if (path == NULL) { errno = EFAULT; return (-1); } #endif
1.11	20-Nov-1998	kleink	Need to wrap stdio stream locking around the function body. On the bright side, getchar_unlocked() can now be used instead of getchar().
1.10	03-Feb-1998	perry	remove obsolete register declarations
1.9	04-Nov-1997	thorpej	__warn_references and __indr_reference semicolon fixups. From Chris Demetriou <cgd@pa.dec.com>.
1.8	13-Jul-1997	christos	branches: 1.8.2; Fix RCSID's Fix gcc warnings. Add prototypes for functions that were declared in more than one place to local.h or extern.h and use that instead.
1.7	02-Feb-1995	jtc	Merged with 4.4lite. Changed to conform to NetBSD's new RCS Id convention.
1.6	21-Jul-1994	jtc	Converted to use link-time warning messages.
1.5	24-Apr-1994	mycroft	branches: 1.5.2; Get rid of extra calls to strlen().
1.4	24-Apr-1994	mycroft	Print the name of the program using a deprecated function.

1.16.36.1	17-Apr-2012	yamt	sync with head
1.17.2.1	20-Aug-2014	tls	Rebase to HEAD as of a few days ago.
1.24	06-Aug-2025	kre	Clean up sources (remove temporary hack) Remove the temporary hack added so these could build before O_CLOFORK (etc) became visible to userland. NFCI.
1.23	17-Jul-2025	kre	Libc functions which need to know about O_CLOFORK. These are Ricardo Branco's libc updates for affected functions that use O_CLOFORK &/or FD_CLOFORK. These are currently padded (by me) with temporary additions so they build while the O_CLOFORK/FD_CLOFORK definitions remain hidden to userland.
1.22	20-Jan-2024	christos	branches: 1.22.2; Catch up with all the lint warnings since exit on warning was disabled. Disable 'missing header declaration' and 'nested extern' warnings for now.

1.18	18-Jun-2014	christos	add mkostemp, mkostemps, mkstemps from FreeBSD.
1.17	21-Jan-2014	seanb	branches: 1.17.2; Handle case where a 0 length template string or a template of all 'X' would dereference, and maybe assign to, memory before the template. Simplify.
1.16	22-Apr-2013	christos	PR/47757: Eric Radman: mktemp(3) mangles the pathname if not given an absolute path 1. on error, gettemp() did not restore the path string 2. when emulating mktemp() it is not an error for the pattern not to represent a real directory structure XXX[1]: pullup-5, pullup-6 XXX[2]: the default pattern is the simplistic <pid><X> for mktemp.
1.15	15-Mar-2012	christos	branches: 1.15.2; - ansify, knf. - no functional changes
1.14	20-Oct-2008	apb	branches: 1.14.2; 1.14.4; 1.14.20; 1.14.22; The tools/compat versions of mkstemp() and mkdtemp() need to call the internal function that's usually named "__gettemp". However in a cross build, "__gettemp" is in a namespace reserved for the host system, so we can't use that. Use "__nbcompat_gettemp" instead, following the example of several other functions or macros in tools/compat. Previously, this was handled by using the name "gettemp", but that conflicts with the local gettemp() function in dist/nawk.
1.13	05-Dec-2003	uebayasi	Spaces.
1.12	27-Oct-2003	lukem	Overhaul how `build.sh tools' are used: * Rename "config.h" to "nbtool_config.h" and HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H. This makes in more obvious in the source when we're using tools/compat/config.h versus "standard autoconf" config.h * Consistently move the inclusion of nbtool_config.h to before <sys/cdefs.h> so that the former can provide __RCSID() (et al), and there's no need to protect those macros any more. These changes should make it easier to "tool-ify" a program by adding: #if HAVE_NBTOOL_CONFIG_H #include "nbtool_config.h" #endif to the top of the source files (for the general case).
1.11	23-Oct-2003	jmc	Move include for reentrant.h inside CONFIG_H test so this works correctly with tools/compat. Fixes PR#21344
1.10	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22280, verified by myself.

1.6	31-Mar-2002	bjh21	Add mkdtemp to libnbcompat, since glibc doesn't have it an mktemp(1) will need it.
1.5	20-Sep-1999	lukem	branches: 1.5.10; back out the #ifdef _DIAGNOSTIC argument checks; too many people complained. _DIAGASSERT() is still retained.

Make f{g,s}etpos() use the new fpos_t struct, while providing backwards compatible entry points. Approved by releng@
1.30	17-Jul-2011	joerg	branches: 1.30.2; Retire varargs.h support. Move machine/stdarg.h logic into MI sys/stdarg.h and expect compiler to provide proper builtins, defaulting to the GCC interface. lint still has a special fallback. Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and derive va_list as required by standards.

1.24	11-Jan-2010	joerg	Use a proper char */size_t pair in __sfileext to keep track of the line buffer for fgetln and fgetwln. Simplifies code by dropping the INT_MAX related logic. Drop conditionals around FREELB, free(NULL) is valid.
1.23	02-Dec-2009	roy	Reinstate __getdelim which does no locking. Callers are now required to FLOCKFILE so they can operate on fp as well.
1.22	01-Dec-2009	roy	Remove __getdelim and just use getdelim. fgetstr now works with strings up to SSIZE_MAX as a result, but may reallocate buffers needlessly just like it used to when the buffer size exceeds INT_MAX. fgetstr converts errno EOVERFLOW to EINVAL on getdelim error.
1.21	24-Sep-2009	roy	__getdelim works on strings up to SIZE_MAX - 2 and returns 0 on EOF. getdelim works on strings up to SSIZE_MAX and returns -1 on EOF. __fgetstr is now just a wrapper around __getdelim and ensures that the buffer doesn't overflow the one provided by FILE. __slbexpand is now static in fgetwln as it is the only consumer of that func.
1.20	14-May-2005	christos	Add the missing wide char support functions from freebsd. XXX: long double support is missing until we get gdtoa, and add the necessary wide functions.
1.19	09-Feb-2005	kleink	A little libc namespace housekeeping exercise: * Make vfprintf_unlocked() an internal function, c.f. __svfscanf_unlocked(). * Add internal names for arc4random(), endnetpath(), fhstatvfs(), fstatvfs(), mkstemp(), shquote(), statvfs(), taddr2uaddr(), uaddr2taddr(), uuid_create_nil(), uuid_is_nil(), and wcwidth(). * Include namespace.h where supposed to.
1.18	10-May-2004	drochner	After discussion with christos, turn fgetstr() into an internal function. Its API in inherently non-threadsafe (and it depends on certain properties of the underlying stdio implementation), so it shouldn't be a first-class function for general use, polluting the application namespace. Also remove the FLOCKFILE() code from it - this is under control of the calling function now. (XXX I'm not sure whether the FLOCKFILE() should be kept in fgetln(), this function cannot be used in multiple threads anyway. It doesn't hurt much, and it might prevent corruption of internal FILE structures.)
1.17	07-Aug-2003	agc	Move UCB-licensed code from 4-clause to 3-clause licence. Patches provided by Joel Baker in PR 22280, verified by myself.
1.16	18-Jul-2003	nathanw	Move guts of flockfile()/funlockfile() to __flockfile_internal(), which takes an additional argument indicating whether this is an internal caller taking the lock or an external (application) caller. When making an internal lock, save the current thread cancellation state and disable cancellation until the matching unlock. This should prevent canccelled threads from exiting inside of stdio while holding a file lock and potentially leaving other parts of the FILE structure in an inconsistent state.
1.15	07-Mar-2003	tshiozak	add fgetws() and fputws() (lib/20576). Note: fgetws.c, fgetws.3, fputws.c and fputws.3 are obtained from FreeBSD, and fitted by sigsegv@infoseek.jp and me.
1.14	01-Feb-2003	nathanw	Revert the conversion to libpthread's recursive mutexes. Too much trouble is caused by the memory allocation in the mutex initialization, and uncontested mutexes and condition variables have become faster in the meantime.
1.13	21-Jan-2003	nathanw	Use recursive mutexes from libpthread rather than implementing our own with normal mutexes and condition variables.
1.12	18-Jan-2003	thorpej	Merge the nathanw_sa branch.
1.11	24-May-2002	thorpej	* Move the prototype of __svfscanf from <stdio.h> to libc/stdio/local.h. * Add prototype for vfscanf to <stdio.h>. * Remove #define of vfscanf to __svfscanf from <stdio.h>. * Include local.h in libc files which need __svfscanf. * Add vfscanf weak alias to __svfscanf. Fixes standards/16997. NOTE: libc minor not bumped -- ride on the bump to 12.84 made by itojun today.

I've left the _DIAGASSERT's that make sure that s != NULL alone because we should really still abort in a debugging environment.

1.6	13-Aug-1996	explorer	Cute little bug with operator precedence in our stdio code. It appears that flushing wasn't done right when input buffers were refilled, due to a check like if (foo == _A \| _B) which, since _A and _B are both != 0, always evaluates to true. Found by proven@cygnus.com

Like Plauger's implementation in "The Standard C Library", we use strtod(), which will limit the range of values that can be converter properly if long double has greater precision or range than double. We will need a string to long double function to handle this properly, but this change is better than the previous behavior of ignoring the existance of long doubles.

Fix for issue reported in PR lib/35401 as well as related overflow bugs. deal with hex doubles. Instead of abusing stdio to get a signal-safe version of sprintf, provide one. remove __SAFE add long double and hex double support from freebsd. make this compile. add new prototypes. add the new files to the build. Note I am not bumping libc now, because these are not used yet. Merge the int bit with the high fraction bit. Add constants/macros needed by gdtoa. add constants used by gdtoa since the int bit is merged, do the explicit math. ext_int bit is no more. ext_int bit is no more. - merge change from freebsd - add support for building as vfprintf.c - XXX: we strdup to simplify the freeing logic. This should be fixed for efficiency in the vfprintf case. use vfwprintf.c enable wide doubles. some int -> size_t deal with sparc64 that has 112 bits of mantissa. make extended precision gdtoa friendly. int/size_t changes make this gdtoa friendly. remove dup definition use dtoa() instead of returning empty when we don't have extended precision information. Fix previous, add forgotten pointer dereference in the call to dtoa(). Add a cheesy workaround marked XXX for the situation where the strtod() implementation available in the environment does not handle hex floats. Discussed with and suggested by christos From Christos: gdtoa fixes for m68k. M68k ports should build now, but printing extended precision is a little off. vax does not have <machine/ieee.h> or long double It would be nice if the compiler provided something like __IEEE_MATH__ bring in FreeBSD's vfscanf() to gain multi-byte/collation support. Unfortunately it is too difficult to make vfwscanf and this share the same code like I did with printf, because for string parsing the code is too different.

1.11.10.5	02-May-2002	nathanw	Call the _unlocked versions of vfprintf() and __svfscanf(); there's no point in locking and unlocking a FILE object that only exists in the local scope. This also has the nice side effect of making sprintf() usable for debugging threaded code.
1.11.10.4	07-Feb-2002	nathanw	Revert previous; this will be done a different way.
1.11.10.3	07-Feb-2002	nathanw	sscanf() and vsscanf() construct private FILE structures; be sure to initialize the flockfile() locks there, too.

1.23	04-May-2010	jruoho	Remove the list of functions. This list was updated only two times in nearly two decades. (If people need to learn the standard I/O functions in C, it would be better to mention K&R or some other textbook; if people need to know the list of functions, it would be better to point out the location of the standard.)

1.21	27-Mar-2012	christos	branches: 1.21.2; - widen the internal read and write calls to match the syscalls - add funopen2() which provides access to flush() and the wider calls. - make use of the new flush call in fmemopen()

1.18	13-Mar-2012	christos	PR/45989: Martin Husemann: lint invocation does include -w only on i386 - turn lint -w for all the platforms after fixing the lint warnings. - add _DIAGASSERTS() for casts that would assign values to types that would not fit. - change types, add casts - change into ansii prototypes - turn on _DIAGNOSTIC for libc (during current, to be eliminated for release builds) approved by core@
1.17	22-Jan-2012	christos	From tnozaki@: make fpos_t a complex object that keeps track of the parse state of the stream. Change argument of the seek function to funopen() from fpos_t to off_t. Make f{g,s}etpos() use the new fpos_t struct, while providing backwards compatible entry points. Approved by releng@

1.14	13-Mar-2008	christos	Since _file is a short, check that the fd fits in it, otherwise bail with EMFILE. We treat _file as an unsigned short to double our range, with a special case for -1 (closed). Make a note of what we should do about stdio if we ever bump libc. We could change _file in the future compatibly to an int by putting it in the extension space but for now we don't bother.

1.17	02-May-1995	jtc	The C Standard says that printf's format string is a multi-byte character string. NA1 says that the 99 characters required by the Standard have representations in the initial state which are one byte long and do not alter the state. Thus we can safely break apart the format string with mbtowc() until we reach a '%' character, and the process format directive characters one by one. We really shouldn't be using mbtowc(), rather mbrtowc() (which takes a mbstate-t argument) but we don't have the NA1 functions implemented yet. This is safe, because even when we do we're not likely to support multi-byte character encodings that use shift states.

Discussed with and suggested by christos From Christos: gdtoa fixes for m68k.

Fix for issue reported in PR lib/35401 as well as related overflow bugs. deal with hex doubles. Instead of abusing stdio to get a signal-safe version of sprintf, provide one. remove __SAFE add long double and hex double support from freebsd. make this compile. add new prototypes. add the new files to the build. Note I am not bumping libc now, because these are not used yet. Merge the int bit with the high fraction bit. Add constants/macros needed by gdtoa. add constants used by gdtoa since the int bit is merged, do the explicit math. ext_int bit is no more. ext_int bit is no more. - merge change from freebsd - add support for building as vfprintf.c - XXX: we strdup to simplify the freeing logic. This should be fixed for efficiency in the vfprintf case. use vfwprintf.c enable wide doubles. some int -> size_t deal with sparc64 that has 112 bits of mantissa. make extended precision gdtoa friendly. int/size_t changes make this gdtoa friendly. remove dup definition use dtoa() instead of returning empty when we don't have extended precision information. Fix previous, add forgotten pointer dereference in the call to dtoa(). Add a cheesy workaround marked XXX for the situation where the strtod() implementation available in the environment does not handle hex floats. Discussed with and suggested by christos From Christos: gdtoa fixes for m68k. M68k ports should build now, but printing extended precision is a little off. vax does not have <machine/ieee.h> or long double It would be nice if the compiler provided something like __IEEE_MATH__ bring in FreeBSD's vfscanf() to gain multi-byte/collation support. Unfortunately it is too difficult to make vfwscanf and this share the same code like I did with printf, because for string parsing the code is too different.

Fix for issue reported in PR lib/35401 as well as related overflow bugs. deal with hex doubles. Instead of abusing stdio to get a signal-safe version of sprintf, provide one. remove __SAFE add long double and hex double support from freebsd. make this compile. add new prototypes. add the new files to the build. Note I am not bumping libc now, because these are not used yet. Merge the int bit with the high fraction bit. Add constants/macros needed by gdtoa. add constants used by gdtoa since the int bit is merged, do the explicit math. ext_int bit is no more. ext_int bit is no more. - merge change from freebsd - add support for building as vfprintf.c - XXX: we strdup to simplify the freeing logic. This should be fixed for efficiency in the vfprintf case. use vfwprintf.c enable wide doubles. some int -> size_t deal with sparc64 that has 112 bits of mantissa. make extended precision gdtoa friendly. int/size_t changes make this gdtoa friendly. remove dup definition use dtoa() instead of returning empty when we don't have extended precision information. Fix previous, add forgotten pointer dereference in the call to dtoa(). Add a cheesy workaround marked XXX for the situation where the strtod() implementation available in the environment does not handle hex floats. Discussed with and suggested by christos From Christos: gdtoa fixes for m68k. M68k ports should build now, but printing extended precision is a little off. vax does not have <machine/ieee.h> or long double It would be nice if the compiler provided something like __IEEE_MATH__ bring in FreeBSD's vfscanf() to gain multi-byte/collation support. Unfortunately it is too difficult to make vfwscanf and this share the same code like I did with printf, because for string parsing the code is too different.

1.2.2.2	22-May-2014	yamt	sync with head. for a reference, the tree before this commit was tagged as yamt-pagecache-tag8. this commit was splitted into small chunks to avoid a limitation of cvs. ("Protocol error: too many arguments")
1.2.2.1	17-Apr-2012	yamt	sync with head
1.3.2.1	23-Jun-2013	tls	resync from head
1.12	17-May-2013	joerg	Provide explicit LC_C_LOCALE accessor and drop the various NULL checks. Provide LC_GLOBAL_LOCALE in a way that works with all locale functions. Merge constant data used by the initial global locale and the C locale. Drop function call layer for _current_locale() and directly return the locale reference, not a pointer to it. Use protected access for global variables, so that libc references can avoid the GOT overhead.
1.11	22-Apr-2013	joerg	Add new line at the end.
1.10	19-Apr-2013	joerg	Add scanf_l and wscanf_l families.
1.9	27-Mar-2012	christos	branches: 1.9.2; - widen the internal read and write calls to match the syscalls - add funopen2() which provides access to flush() and the wider calls. - make use of the new flush call in fmemopen()

1.7	13-Mar-2012	christos	PR/45989: Martin Husemann: lint invocation does include -w only on i386 - turn lint -w for all the platforms after fixing the lint warnings. - add _DIAGASSERTS() for casts that would assign values to types that would not fit. - change types, add casts - change into ansii prototypes - turn on _DIAGNOSTIC for libc (during current, to be eliminated for release builds) approved by core@
1.6	11-Jan-2010	joerg	branches: 1.6.6; Use a proper char */size_t pair in __sfileext to keep track of the line buffer for fgetln and fgetwln. Simplifies code by dropping the INT_MAX related logic. Drop conditionals around FREELB, free(NULL) is valid.
