Currently I am doing ATM Network Simulation for my final project. The ATM 
Network Simulator is running in Linux using X-Windows but at the same 
time it can be run without using X-Windows in background mode. Every time 
the simulator finished running, it produces an output file in the same 
directory and it is in this form "SIM_SNAP.XXX". The "XXX" is a number (3 
digit). I think the number is the process id. If it is the process id 
then how can I read this file without knowing the process. I am 
running the simulator from another C program that is I am calling 
the.exe file using exec() function. How can I read the output file 
which the name is not specified???
Can anyone guide me???

Thanks...
