Determine whether or not an offscreen context is locked
int PdIsOffscreenLocked( PdOffscreenContext_t *osc );
ph
This function tests to see if the given offscreen context is currently locked.
This is really only useful for debugging purposes, because the state of the lock could potentially change between the time that PdIsOffscreenLocked() queries the status and reports it back to the application. |
