project Query about fork() (both)

4:03pm Mon 6th May, ANONYMOUS

Hello Sir, I have started my project implementation using Beej's guide. In the project specification, it states there shouldn't be any reliance on a shared file system or any other inter process communication mechanisms. Beej's guide uses the fork() system call, is this allowed according to the project specifications.

Yes, you may use fork(), provided that the parent and child only communication using socket-based protocols. But I'm encouraging you to seriously ask - why do you need a new heavy-weight process, presumably to do nothing beyond sending a request and waiting for its reply? Most of the time, that new process will simply be blocked, waiting for that single reply.
