I'm working with W. Richard Sevens's book "Advanced Programming in the
Unix Environment". Currently I'm working with a sample application he
calls an "open server". In it, one process passes an opened file
descriptor to another process.
He shows three examples of how to do it on SVR4, 4.3BSD and 4.3+BSD
implementations of Unix, none of which will compile on my Linux system.
Can this be done? I'll supply more detail if needed.
