I hope I haven't caused any confusion, it's been a while since I used redir, so
I may have muddled the command line options (I thought above would work though,
stdout > stderr, then stderr > error.log).

They are the standard C++ file handles for input (stdin), output (stdout) and
error reporting (stderr). They are basically a FILE *, but they are redirected
to hardware devices by default. stdin comes from the keyboard, stdout and stderr
go to the screen (by default). So, when you say printf("Hello World\n"); in your
program, you're actually printing the string to stdout.

Do you actually have redir in your DJGPP/bin directory? And the DJGPP/bin
directory on your PATH?

DJGPP comes with offline documentation as well in the form of the Info program.
Type info redir at the prompt for the redir docs, or just info for a directory
of docs.
