Inter-Process Communication (IPC) is the subject of spawning and controlling other programs or "processes" from within perl (sometimes using sockets to do so). The subject is briefly discussed in the perlipc(1) man page, and was addressed towards the end of Chapter 6 of The Camel. The subject is also discussed in the perl FAQ and at Tom Christiansen's ftp site (in the various perlipc* files) at:
ftp://ftp.perl.com/perl/info/everything_to_know/ 199.45.129.30as well as the web site at:
http://www.perl.com/perl/everything_to_know/ipc/index.htmlIn addition to the usual perl IPC routines Tk allows (at least) three more special functions: fileevent (for handling I/O events), send (for inter-widget communication), and after (for time control like a sleep expressly for widgets).
Remember:
If a packet hits a pocket on a socket on a port,
And the bus is interrupted as a very last resort,
And the address of the memory makes your floppy disk abort,
Then the socket packet pocket has an error to report!
-Ken Burchill(?)
