1 The libbacktrace library 2 Initially written by Ian Lance Taylor <iant (a] golang.org> 3 4 The libbacktrace library may be linked into a program or library and 5 used to produce symbolic backtraces. 6 Sample uses would be to print a detailed backtrace when an error 7 occurs or to gather detailed profiling information. 8 In general the functions provided by this library are async-signal-safe, 9 meaning that they may be safely called from a signal handler. 10 11 The libbacktrace library is provided under a BSD license. 12 See the source files for the exact license text. 13 14 The public functions are declared and documented in the header file 15 backtrace.h, which should be #include'd by a user of the library. 16 17 Building libbacktrace will generate a file backtrace-supported.h, 18 which a user of the library may use to determine whether backtraces 19 will work. 20 See the source file backtrace-supported.h.in for the macros that it 21 defines. 22 23 As of October 2020, libbacktrace supports ELF, PE/COFF, Mach-O, and 24 XCOFF executables with DWARF debugging information. 25 In other words, it supports GNU/Linux, *BSD, macOS, Windows, and AIX. 26 The library is written to make it straightforward to add support for 27 other object file and debugging formats. 28 29 The library relies on the C++ unwind API defined at 30 https://itanium-cxx-abi.github.io/cxx-abi/abi-eh.html 31 This API is provided by GCC and clang. 32
