# libbacktrace
|
||
|
|
A C library that may be linked into a C/C++ program to produce symbolic backtraces
|
||
|
|
|
||
|
|
Initially written by Ian Lance Taylor <iant@golang.org>.
|
||
|
|
|
||
|
|
This is version 1.0.
|
||
|
|
It is likely that this will always be version 1.0.
|
||
|
|
|
||
|
|
The libbacktrace library may be linked into a program or library and
|
||
|
|
used to produce symbolic backtraces.
|
||
|
|
Sample uses would be to print a detailed backtrace when an error
|
||
|
|
occurs or to gather detailed profiling information.
|
||
|
|
In general the functions provided by this library are async-signal-safe,
|
||
|
|
meaning that they may be safely called from a signal handler.
|
||
|
|
|
||
|
|
The libbacktrace library is provided under a BSD license.
|
||
|
|
See the source files for the exact license text.
|
||
|
|
|
||
|
|
The public functions are declared and documented in the header file
|
||
|
|
backtrace.h, which should be #include'd by a user of the library.
|
||
|
|
|
||
|
|
Building libbacktrace will generate a file backtrace-supported.h,
|
||
|
|
which a user of the library may use to determine whether backtraces
|
||
|
|
will work.
|
||
|
|
See the source file backtrace-supported.h.in for the macros that it
|
||
|
|
defines.
|
||
|
|
|
||
|
|
As of October 2020, libbacktrace supports ELF, PE/COFF, Mach-O, and
|
||
|
|
XCOFF executables with DWARF debugging information.
|
||
|
|
In other words, it supports GNU/Linux, *BSD, macOS, Windows, and AIX.
|
||
|
|
The library is written to make it straightforward to add support for
|
||
|
|
other object file and debugging formats.
|
||
|
|
|
||
|
|
The library relies on the C++ unwind API defined at
|
||
|
|
https://itanium-cxx-abi.github.io/cxx-abi/abi-eh.html
|
||
|
|
This API is provided by GCC and clang.
