As many other programs...

I'm not sure what you mean by "non-standard file descriptors". The 
other program is free to open, read, write, etc any file he wants - 
are you trying to trap any file operation it may want to do?
You *could* do such things -google for "code injection" and "API 
hooking"- but I doubt it's what you really want.
