Hi folks.
I'm using the Intek C++ compiler on a 386 PC running DOS 4.0.
This compiler outputs its error messages to stderr, so I cannot use
the redirection character ">" at the command level to save the output
in a file.
Does anyone have a hack that will modify DOS to overlap stderr onto
stdout?
I tried writing a short assembly program that uses DOS INT 21H,
function 46H (CDUP) to force stderr to output to stdout, but it didn't
work. I'm not very knowledgable with the DOS interrupts, so my
understanding of CDUP's operation may be wrong.
I also retrieved REDIRECT.C from Simtel20, but it didn't solve my
problem. In fact it causes a stack overflow error. Part of the
problem might stem from the compiler switching the 386 into protected
mode to take advantage of extended memory and then switching back to
real mode when it's done.
Thanks in advance for any help.

As far as I know, dos (the command.com shell acutally) does not allow redirecting standard error. Two solutions occur to me. 4dos, (an improved shell) will run under dos 4.0 I believe, and it allows separate re-direction of stdout, plus many other goodies. I recommend it. A dos solution might be to write a small c program that re-opens standard error to a file and then spawns your process. I can't say for your particular case, but I have in the past used this method with success. Rick

Part of Microsoft C 5.x is a program called ERROUT which does the
redirection of errout to any other channel. It's not bundled with 6.0
