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 in-
crements the semaphores value. Threads that were blocking on the sema-
phore may be scheduled after this call succeeds.
SDL_SemPost should be called after a semaphore is locked by a success-
ful call to SDL_SemWait, SDL_SemTryWait or SDL_SemWaitTimeout.
RETURN VALUE
Returns 0 if successful or -1 if there was an error (leaving the sema-
phore unchanged).
EXAMPLES
SDL_SemPost(my_sem);
