# 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> |
||||
|
||||
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. |
||||
|
||||
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 September 2016, libbacktrace only supports ELF and PE/COFF |
||||
executables with DWARF debugging information. |
||||
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 |
||||
http://mentorembedded.github.io/cxx-abi/abi-eh.html. |
||||
This API is provided by GCC. |
