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.
Description:
The bt_sprn_memmap() function formats the memory map information into out.
Note:
The out string might not be null-terminated.
Returns:
- 0
- Success.
- -1
- An error occurred
