But if both your processes are on the same machine you can use a pipe
which is even easier than a socket albeit less flexible. But a pipe
just looks like a file you read from - the popenX() family is the
function set to look at.

But your file processing solution is a perfectly valid way of working,
especially for large data volumes. Its how almost every mainframe
application in existence works! The big win is ease of data and/or job
recovery in the event of a crash.
