WebNotes on single slot bounded buffer •Semaphores empty and full are binary semaphores –Their values are restricted to {0,1}; general semaphores need only have a nonnegative value •Note that weare ensuring that the values are restricted {0,1} (not the semaphore mechanism). •Further, empty and full are split binary semaphores WebRemoving a semaphore structure can only be done by the user ID of the creator of the semaphore structure. This can be done on the command line using ipcrm semaid, or you can explicitly remove the semaphore structure within the program using semctl int semctl (semid, 0, IPC_RMID, 0) You will find more details at FAQ.
