bt_release_accessor()

Updated: October 26, 2022

Release an accessor 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_release_accessor(bt_accessor_t *acc);

Arguments:

acc
A pointer to a bt_accessor_t structure. This is an opaque structure that holds the identity of the thread to backtrace.

Library:

libbacktrace

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

Description:

The bt_release_accessor() function releases all resources that acc keeps track of.

Note: Don't release an accessor while another function is using it.

Don't call bt_init_accessor() or bt_release_accessor() for the bt_acc_self global variable.

Returns:

0
Success.
-1
An error occurred (errno is set).

Errors:

EINVAL
The acc argument is NULL.
