I would like to redirect some of the output of a program I usually run as
xterm -e program into a separate X window.
Why doesn't the following work?

{
	FILE *f;
	f = open ( "/tmp/zap", "w" );
	system "/usr/local/bin/X11R4/xterm -e cat /tmp/zap";

	... here I use fprintf(f,...); for writing to that X window
	    and fprintf(stdout,...); for writing to the X window in
	    which the program was started ...

	fclose(f);
}
	
I gather xterm's stdin, and stdout are not the same as cat's.
I don't really want lots of X wizardry in my program...

Thanks,
	Kees
