SDL_CreateSemaphore(3)	       SDL API Reference	SDL_CreateSemaphore(3)

NAME
       SDL_CreateSemaphore  -  Creates	a new semaphore and assigns an initial
       value to it.

SYNOPSIS
       #include "SDL.h" #include "SDL_thread.h"

       SDL_sem *SDL_CreateSemaphore(Uint32 initial_value);

DESCRIPTION
       SDL_CreateSemaphore() creates a new semaphore and initializes  it  with
       the  value  initial_value.  Each	 locking operation on the semaphore by
       SDL_SemWait,  SDL_SemTryWait  or	 SDL_SemWaitTimeout  will   atomically
       decrement the semaphore value. The locking operation will be blocked if
       the semaphore value is not positive (greater than  zero).  Each	unlock
       operation by SDL_SemPost will atomically increment the semaphore value.

RETURN VALUE
       Returns	a  pointer to an initialized semaphore or NULL if there was an
       error.

EXAMPLES
       SDL_sem *my_sem;

       my_sem = SDL_CreateSemaphore(INITIAL_SEM_VALUE);

       if (my_sem == NULL) {
	       return CREATE_SEM_FAILED;
       }
