#include <mqueue.h>
int mq_close(mqd_t mqdes);
Link with −lrt.
mq_close() closes the message queue descriptor mqdes.
If the calling process has attached a notification request to this message queue via mqdes, then this request is removed, and another process can now attach a notification request.
On success mq_close() returns 0; on error, −1 is returned, with errno set to indicate the error.
