DESCRIPTION

14       SDL_SemPost  unlocks  the  semaphore  pointed  to by sem and atomically
15       increments the semaphores value. Threads that were blocking on the sem‐
16       aphore may be scheduled after this call succeeds.
17
18       SDL_SemPost  should be called after a semaphore is locked by a success‐
19       ful call to SDL_SemWait, SDL_SemTryWait or SDL_SemWaitTimeout.
20

RETURN VALUE

22       Returns 0 if successful or -1 if there was an error (leaving the  sema‐
23       phore unchanged).
