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. |
#include <backtrace.h>
int bt_release_accessor(bt_accessor_t *acc);
- acc
- A pointer to a bt_accessor_t structure.
This is an opaque structure that holds the identity of the thread to
backtrace.
libbacktrace
Use the -l backtrace option to
qcc
to link against this library.
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. |
- 0
- Success.
- -1
- An error occurred
(errno
is set).
- EINVAL
- The acc argument is NULL.
