SDL_SemPost(3) SDL API Reference SDL_SemPost(3) NAME SDL_SemPost - Unlock a semaphore. SYNOPSIS #include "SDL.h" #include "SDL_thread.h" int SDL_SemPost(SDL_sem *sem); DESCRIPTION SDL_SemPost unlocks the semaphore pointed to by sem and atomically incre- ments 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. RETURN VALUE Returns 0 if successful or -1 if there was an error (leaving the semaphore unchanged). EXAMPLES SDL_SemPost(my_sem); SEE ALSO SDL_CreateSemaphore, SDL_DestroySemaphore, SDL_SemWait, SDL_SemTryWait, SDL_SemWaitTimeout, SDL_SemValue SDL Tue 11 Sep 2001, 23:00 SDL_SemPost(3)
