Re: Redirecting output

[günther <guenther rapp-informatik de>]

I did it this way with a yacc and lex problem.
The main problem is that you have to have two asynchrony
processes, because any action in the callback only takes place
if this the callback has finished .
The best way is to use gtk threads (have a look on the documentation)
Readirect stderr or stdout to a named pipe open (take care of blocking
open with
no block) . In the 2nd thread open this
pipe for read and show a error dialog.

I hopw it will help.
