I have 2 applications on the same system that I need to communicate back and forth. From my research I believe this is called Inter Process Communication and the use of socketpair() is the best method for my problem.
I am tearing my hair out (literally) trying to get started with creating sockets with socketpair() in C. From what I understand, sockets are a very complex topic and me being a novice C programmer is surely not helping the situation.
I googled for the last 48 hours, read tutorials, etc, but I still can't get it. I understand the concept, but the code is just too confusing. I've read this article a few times: http://beej.us/guide/bgnet/html/single/bgnet.html, but it's not simple enough.
Can someone provide some example (so simple a 5th grader could understand) or point me to a good tutorial?
