sem_unlink - remove a named semaphore
#include <semaphore.h> int sem_unlink(const char *name); Link with -lrt or -pthread.
sem_unlink() removes the named semaphore referred to by name. 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.
EACCES The caller does not have permission to unlink this semaphore. ENAMETOOLONG name was too long. ENOENT There is no semaphore with the given name.
