#include <mqueue.h>
int mq_unlink(const char *name);

mq_unlink() removes the specified message queue name. The message queue name is removed immediately. The queue itself is destroyed once any other processes that have the queue open close their descriptors referring to the queue.

On success mq_unlink() returns 0; on error, -1 is returned, with errno set to indicate the error.
