For background C applications, there is no "easy" way to know. You can technically issue the "top" command to the system shell:


system "top"


and then parse the response to see if your program is listed (e.g. capp1.out). Top is a Linux command that shows running processes:




There might be a cuter Linux command out there, but I am not an expert on it.


It is much easier, though, to put a global variable that increments as the program runs, for example, and then just check if that variable is incrementing to verify that the program is running.
