Recently I’ve been trying to understand the concept of interprocess communication in C. I’ve looked at some example code, read the man pages for fork() dup() pipe(), exevc() and the like; but the concept just wouldn’t sink in.
Luckily, someone I met from the Kirupa Forums, njs54345 said to search google for ‘Beej’. I followed his advice and was happy I did, Beej has some awesome information. I did some small example projects based of the IPC tutorial and posted the source files on the source section of this site. If your trying to learn network, or inter process communication in C I would highly recommend those tutorials- there great.
