[DUG] Sending data between process on same computer on windows

[Conor Boyd]

Sorry Leigh, I haven't done enough testing with big volume messages to
be able to answer that for you.
 
I was more interested in something that worked and was reliable.
 
Cheers,
 
Conor

May I ask which is faster, ipc or sendmessage?

	I found the IPC functionality from madshi.net
(http://help.madshi.net/IPC.htm <http://help.madshi.net/IPC.htm> ) to
work very nicely.
	 
	I needed a way to send messages from a screensaver I was writing
to another process on the same box, and SendMessage didn't seem to work
when a screensaver was active (which I found strange, but anyway...),
and the IPC stuff from madshi works flawlessly.

	May I ask what is the fastest way to send data between process
on same computer on windows? I assume sendmessage api faster than
semaphore waiting, of course faster than TCP/IP which will go through
huge amounts of tcp/ip stack. I just want lowest overhead on per call.
Anyone have any experiences on that?
