sem_unlink − remove a named semaphore
#include <semaphore.h>
int sem_unlink(const char *name);
sem_unlink() removes the named semaphore referred to by sem. The semaphore name is removed immediately. The semaphore is destroyed once all other processes that have the semaphore open close it.
On success sem_unlink() returns 0; on error, −1 is returned, with errno set to indicate the error.
