Hello all,

I am teaching myself a little bit about C by writing a small utility 
on a PC using MS QuickC. In this utility (call it "foo"), I want to 
specify an output file, and from within foo, interactively run some 
other programs I also specify during foo's execution, with foo spooling 
the entire execution session to both the screen (so I can see what I'm 
doing) and the output file (so I have a record). This would be exactly 
like a logging a terminal session on a larger multi-user machine.

I have attempted solving the spooling problem by duplicating file handles 
so that stdout and stderr both point to the output file. This (naive) 
approach failed dismally (as one would expect). I have seen an OS/2 
implementation using pipes, but I am unsure how to work this in QuickC.

I was wondering if anybody could e-mail me any helps/tips/suggestions/
code or information on a utility like this that may already exist. If I 
haven't provided enough information, let me know and I'll show some code.

Thanks for any help that you may be able to provide.

Cheers,
Rob.
