NAME
       semaphore.h, semaphore - semaphores

SYNOPSIS
       #include <semaphore.h>

DESCRIPTION
       The  <semaphore.h>  header  defines  the sem_t type, used in performing
       semaphore operations. The semaphore can be  implemented	using  a  file
       descriptor,  in	which case applications are able to open up at least a
       total of {OPEN_MAX} files and  semaphores.  The	symbol	SEM_FAILED  is
       defined (see sem_open(3RT)).

       Inclusion  of the <semaphore.h> header can make visible symbols defined
       in the headers <fcntl.h>	 and  <sys/types.h>.  See  fcntl.h(3HEAD)  and
       types.h(3HEAD).
