Function Documentation

vlc_queuedmutex_held()

bool vlc_queuedmutex_held

(

vlc_queuedmutex_t *

m

)

Checks if a queued mutex is locked.

This function checks if the calling thread holds a given queued mutual exclusion lock. It has no side effects and is essentially intended for run-time debugging.

Note

To assert that the calling thread holds a lock, the helper macro vlc_queuedmutex_assert() should be used instead of this function.

Return values

false	the mutex is not locked by the calling thread
true	the mutex is locked by the calling thread
