bt_unload_memmap()

Unload a memory map associated with a backtrace

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:

libbacktrace

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

Description:

The bt_unload_memmap() function releases the memory that memmap holds. Don't use memmap after invoking this function.

Classification:

QNX Neutrino

Safety:
Cancellation point	No
Interrupt handler	No
Signal handler	No
Thread	Yes
