atomic_op (ULTRIX)					    atomic_op (ULTRIX)

NAME
       msem_init,  msem_lock,  msem_unlock,  msem_remove  - Semaphore function
       calls

DIFFERENCES
       On an ULTRIX system, semaphores are done through	 the  atomic_op	 call.
       This  call  allows  you	to  test and set a user-space address that you
       specify. The Digital UNIX system does not contain the  atomic_op	 call.
       However,	 the  system  does include library routines that perform sema‐
       phore operations.

       The Digital UNIX library functions are as follows:

       * msem_init, which initializes a semaphore

       * msem_lock, which locks a semaphore

       * msem_unlock, which unlocks a semaphore

       * msem_remove, which removes a semaphore

RELATED INFORMATION
