mq_unlink
mq_unlink(2) System Calls Manual mq_unlink(2) NAME
mq_unlink - unlink a message queue SYNOPSIS
DESCRIPTION
The system call disassociates the queue name, from a message queue specified by the argument, name. After a successful call to attempts to open a message queue with the same name will fail, if the flag is not set in oflags. If there are no processes with existing open descriptors for the message queue, the queue is destroyed. If one or more processes have the message queue open, the removal of the queue is postponed until all descriptors for the queue have been closed. To use this function, link in the realtime library by specifying on the compiler or linker command line. Security Restrictions Some or all of the actions associated with this system call are subject to compartmentalization restrictions. See compartments(5) for more information. Some or all of the actions associated with this system call require privileges. See privileges(5). RETURN VALUE
returns the following values: Successful completion. Failure, is set to indicate the error. ERRORS
If fails, is set to one of the following values: [EACCES] Permission to unlink the named message queue is denied. [EINVAL] The argument name is not a valid message queue name. [ENAMETOOLONG] The length of the name string exceeds bytes, or the length of a (pathname) component of the name string exceeds bytes while is in effect. [ENOENT] The named message queue does not exist. [ENOSYS] is not supported by the implementation. SEE ALSO
