sem_close − close a named semaphore
#include <semaphore.h>
int sem_close(sem_t *sem);
sem_close() closes the named semaphore referred to by sem, allowing any resources that the system has allocated to the calling process for this semaphore to be freed.
All open named semaphores are automatically closed on process termination, or upon execve(2).
On success sem_close() returns 0; on error, −1 is returned, with errno set to indicate the error.
