Hi,

can anyone show me how to solve the following exercise in ANSI C?

Create 2 process (parent & child).

The parent have to create a file called file<pid>, where <pid> is the process ID of the child process.

For n times (where n is a constant previously defined) the child process and the parent process alternately write in file<pid> a sentence (like "I'm the child" or "I'm the parent") and their process ID.

After n writings the parent process write in file<pid> the termination status of child process.

I hope you understand.. It's so important, please help me!

Thank's!

I'm sorry, we won't do your homework. See point 6 of the rules:

Simple rules of the UNIX.COM forums:

Ask your teacher if you're stuck. (and buy ``Advanced Programming in the UNIX Environment'' by Richard Stevens.)

On a side note, ANSI C does not have the concept of processes. Therefore, what you want is presumably a POSIX or UNIX solution.
