Process-Executer-with-Pooled-Servers-and-Clients-Using-Same-File-System: A C repository from sglbl

Simulating 2 process-pooled servers (Y and Z) executing on the same system as the clients. Which;

Y and Z are daemon processes that have no controlling terminal.
Y is singleton (measure against double instantiation).
Y have p children processes (workers).
If children of Y are already busy, they send requests to Z through pipe.
Z is a server instantiated by Server Y.
Z have children process pool (workers) and delegates requests to its children using shared memory segment.
Client connects to server Y through the server fifo (given as a commandline argument), sends its request, receives its response through its client fifo, prints it to STDOUT and exit. (Also it exits gracefully in case of SIGINT)
