NAME

SDL_SemPost?- Unlock a semaphore.

SYNOPSIS

#include

int SDL_SemPost?(SDL_sem *sem);

DESCRIPTION

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?.

RETURN VALUE

Returns 0 if successful or -1 if there was an error (leaving the semaphore unchanged).

EXAMPLES

SDL_SemPost?(my_sem);
