SDL_SemPost - Unlock a semaphore.

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.

SDL_SemPost(my_sem);

       SDL_SemPost - Unlock a semaphore.

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