Unload a memory map associated with 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>

void bt_unload_memmap( bt_memmap_t *memmap );

Arguments:

memmap
A pointer to the memory map that you want to unload.

Library:
