SDL_SemPost — Unlock a semaphore.
#include "SDL.h" #include "SDL_thread.h"
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.
