Link with -pthread.
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.
On success sem_close() returns 0; on error, -1 is returned, with errno
set to indicate the error.
EINVAL sem is not a valid semaphore.
All open named semaphores are automatically closed on process termina-
tion, or upon execve(2).
