|
|
|
+ * @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 mq_unlink() call need not block until all references have been closed; it may return immediately.
|
|
|
+ *
|
|
|
+ * After a successful call to mq_unlink(), reuse of the name shall subsequently cause mq_open() to behave as if
|
|
|
+ * no message queue of this name exists (that is, mq_open() will fail if O_CREAT is not set,
|
|
|
+ * or will create a new message queue if O_CREAT is set).
|
|
|
+ *
|
|
|
+ * @param name is the name of the message queue.
|
|
|
+ *
|
|
|
+ * @return Upon successful completion, the function shall return a value of zero.
|
|
|
+ * Otherwise, the named message queue shall be unchanged by this function call,
|
|
|
+ * and the function shall return a value of -1 and set errno to indicate the error.
|
|
|
+ *
|
|
|
+ * @warning This function can ONLY be called in the thread context, you can use RT_DEBUG_IN_THREAD_CONTEXT to
|
|
|
+ * check the context.
|
|
|
+ * The mq_unlink() function shall fail if:
|
|
|
+ * [EACCES]
|
|
|
+ * Permission is denied to unlink the named message queue.
|
|
|
+ * [EINTR]
|
|
|
+ * The call to mq_unlink() blocked waiting for all references to the named message queue to be closed and a signal interrupted the call.
|
|
|
+ * [ENOENT]
|
|
|
+ * The named message queue does not exist.
|
|
|
+ * The mq_unlink() function may fail if:
|
|
|
+ * [ENAMETOOLONG]
|
|
|
+ * The length of the name argument exceeds {_POSIX_PATH_MAX} on systems that do not support the XSI option
|
|
|
+ * or exceeds {_XOPEN_PATH_MAX} on XSI systems,or has a pathname component that is longer than {_POSIX_NAME_MAX} on systems that do
|
|
|
+ * not support the XSI option or longer than {_XOPEN_NAME_MAX} on XSI systems.A call to mq_unlink() with a name argument that contains
|
|
|
+ * the same message queue name as was previously used in a successful mq_open() call shall not give an [ENAMETOOLONG] error.
