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.
