Function mq_unlink

components/libc/posix/ipc/mqueue.c:430–440

* @brief This function will remove a message queue (REALTIME). * * @note The mq_unlink() function shall remove the message queue named by the string name. * If one or more processes have the message queue open when mq_unlink() is called, * destruction of the message queue shall be postponed until all references to the message queue have been closed. * However,

 *              the same message queue name as was previously used in a successful mq_open() call shall not give an [ENAMETOOLONG] error.
