bt_release_accessor()

Release an accessor for 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>

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.

---

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.

Classification:

QNX Neutrino
