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.
