mq_close − close a message queue descriptor
#include <mqueue.h>
mqd_t mq_close(mqd_t mqdes);
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.
All open message queues are automatically closed on process termination, or upon execve(2).
On success mq_close() returns 0; on error, −1 is returned, with errno set to indicate the error.

The descriptor specified in mqdes is invalid. |
