    msgrcv ID,VAR,SIZE,TYPE,FLAGS
            Calls the System V IPC function msgrcv to receive a message from
            message queue ID into variable VAR with a maximum message size
            of SIZE. Note that when a message is received, the message type
            as a native long integer will be the first thing in VAR,
            followed by the actual message. This packing may be opened with
            "unpack("l! a*")". Taints the variable. Returns true if
            successful, false on error. See also "SysV IPC" in perlipc and
            the documentation for "[IPC::SysV](https://www.chedong.com/phpMan.php/perldoc/IPC%3A%3ASysV/markdown)" and "[IPC::Msg](https://www.chedong.com/phpMan.php/perldoc/IPC%3A%3AMsg/markdown)".
