I have experimented some with it, but I prefer to use Randall Franks
implementation of sockets (The dll is on my web site at
But yes, sockets are extremely useful for both pure IDL and interfacing with
C programs. I recently helped someone who wanted to run a mix of IDL and C
applications on different machines and pass the results back to a "master"
IDL program for compilation and display. So you can use these to implement a
parallel processing architecture (Shameless plug coming... If anyone is
interested in doing parallel processing with IDL I have something up and
running, just contact me.)
I expect, but haven't tried it, that sockets would be great for applications
that need to access real time information over the web. Something like
weather or stock market data comes to mind.
