jdolecek | for fread(3) and fwrite(3) check for (size * nmemb) size_t overflow, and
error out with EOVERFLOW if it happens; this is less silly answer
to a silly call than returning some randomly wrapped length
change adapted from OpenBSD
FreeBSD has a similar check, but they return EINVAL instead, feel
free to adjust if SUS or other standard mandates specific value

mrg | fixes for GCC 6:
- -Wstrict-prototypes is not available for C++, so don't try to
ignore it for C++.
- remove many _DIAGASSERT() checks against not NULL for functions
with arguments with nonnull attributes. in two cases, leave
code behind that should set defaults to "(null)".
- use -Wno-error=frame-address for i386 mcount, as it seems valid
to assume the caller will have a frame.fair

apparently ansi c only required fread(3) to return 0 if size or nmembs == 0.
however, susv2 adds the same to fwrite(3), so add the explicit check.
document this for both fread & fwrite. move diagassert for buf!=NULL to after
the (size * nmembs) == 0 check.
this has the helpful side effect of preventing the _DIAGASSERT()ion in
fwrite() being triggered by lots of 3rdparty code that calls fwrite() with
buf=NULL count=0

lukem | back out the #ifdef _DIAGNOSTIC argument checks; too many people complained.
_DIAGASSERT() is still retained.
|
| 1.11 |
| 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
|
| 1.10 |
| 16-Sep-1999 |
lukem | return (0) if size or count == 0 before check for _DIAGASSERT(buf != NULL).
this is ok according to SUS.

| 1.9 |

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
