int
SDL_SemPost( |
SDL_sem * | sem) ; |
SDL_SemPost
unlocks the
semaphore pointed to by sem
and atomically increments
the semaphores value. Threads that were blocking on the
semaphore may be scheduled after this call succeeds.
SDL_SemPost
should be called
after a semaphore is locked by a successful call to
SDL_SemWait
, SDL_SemTryWait
or SDL_SemWaitTimeout
.
