Updated: October 26, 2022

Format the memory map information for a backtrace

Note: The backtrace library is an unsupported feature, due to its fragility. For more information, see Backtraces in the QNX Neutrino technotes.

Synopsis:

#include <backtrace.h>

int bt_sprn_memmap( bt_memmap_t *memmap,
                    char *out,
                    size_t outlen );

Arguments:

memmap
A pointer to memory-map information for the process you've collected backtracing for. Use bt_load_memmap() to initialize this variable.
out
A string where the function can store the formatted memory map.
outlen
The size of out.

Library:

libbacktrace

Use the -l backtrace option to qcc to link against this library.
