Synopsis:

In QNX Neutrino 7.1 or later, there are two versions of the forksafe_mutex_*() functions:

Description:

The forksafe_mutex_destroy() function destroys the unlocked forksafe mutex mutex.

You can destroy a locked mutex only if you're the owner of that mutex.

Note: Once you've destroyed a mutex, don't reuse it without reinitializing it by calling forksafe_mutex_init().

For more information about forksafe mutexes, see Using fork() in a multithreaded process in the “Processes and Threads” chapter of Getting Started with QNX Neutrino.

Returns:

EOK
Success.
EBUSY
The mutex is locked by another thread.
EINVAL
Invalid mutex mutex.
