Please tell When you process something, the "normal" output is sent to wherever the process's "stdout" (standard output) is routed, and errors/warning are sent to "stderr" (standard error). If you happen to be running a shell in an xterm, stdout and stderr end up being directed to the "terminal", which is then displayed by xterm. Of course, pipes | and redirection > >> and friends can change where stdout and stderr are sent. For GTK, you want to use a sub-process to run your program, and use pipes to capture the stdout/stderr of the process.
