### 3.2.96 msgsnd

    msgsnd ID, MSG, FLAGS

This function calls the msgsnd(2) system call to send the message `MSG` to the message queue `ID`. See msgsnd(2) for details. `MSG` must begin with the long integer message type. You can create a message like this:

    $msg = pack "L a*", $type, $text_of_message;

The function returns true if successful, or false if there is an error. On error, it puts the error code into $!. Before calling, you should say:

    require "ipc.ph";
    require "msg.ph";

This function is available only on machines supporting System V IPC.
