Way to monitor message queue

Dear monks,

Is it possible to watch message queue for a new message?

We can do this by having a loop and a sleep inside it and check for new messages in the message queue. But, I feel this is not a worthy solution. If no messages are coming then it is of no use to check every time after sleep.

Is there any other way to accomplish this task? similar to select function for sockets

You might/probably want to look at POE.	[reply]

How are the messages queued right now? If you're allowed to change the way messages are queued, consider using a message queue library. For example, POE-Component-MessageQueue. `-- Rocco Caputo - http://poe.perl.org/ - irc://irc.perl.org/poe`	[reply]

What kind of message queue? Tk, Wx, WinNative, Other? Any solution offered without knowledge of the type of message queue is just pointless speculation!

I am referring to Unix IPC message queues, which is a way to send a block of data from one process to another.	[reply]

msgrcv should block waiting for a message unless IPC_NOWAIT is set in the flags.	[reply]
