I am trying to use G_system command to fork a process or to call
an external module. It does not seem to work. However if I use system call
it does work. Any one can explain why it is doing?
Thanks.

Srin,
What is G_system returning? What is your hardware and OS? You
may want to compile with -g and step through it with a debugger.
Specifically, check each signal.
From src/libes/gis/system.c:
|> * This is essentially the UNIX system() call, except for the signal

|> * signals are reset upon completion.
If the child process receives a signal, do you just want it to quit,
or do you want everything to stop?
