The question does not have to be directly related to Linux and any language is fair game.

Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

main(){
int pid;
int i;
for (i = 1; i <= 4; i++){
if(pid != 0)
pid = fork();
}
sleep(10);
}
From those 4 processes i need to use one process as "RECEPTIONIST" & other three as "AGENTS".
To do so, how can i differentiate the processes.
RECEPTIONIST should read from a file and should send those to message queue.
AGENTS should read from that message queue.
(I need to have 1 RECEPTIONIST FUNCTION & 1 AGENT FUNTION.So to which process i should write those functions)
RETURN VALUE
On success, the PID of the child process is returned in the parent’s
thread of execution, and a 0 is returned in the child’s thread of exe-
cution. On failure, a -1 will be returned in the parent’s context, no
child process will be created, and errno will be set appropriately.
so you just check the rtn code from the fork() call, which tells you which process each code is running in.
Call fork() 3 times to use each child as an AGENT, & parent as RECEPTIONIST.
This isn't a homework qn by any chance ...?
