Re: [Dev-C++] how to redirect clog??

[Daniel G. <sp...@ho...>]

can you overload operator =, or define your own operator?

Hello Daniel and all Dev-C++ users,

I think you might be missing something - clog is exactly the same as
cout or cerr - these are just instaces of ostream... I want to use
clog in many parts of my program to send debuging data into file, and
I can easly do it now... eee... I'm programming this code at the
moment...

I think you mean to say that they are *instances*of*the*same*class* - the
way you've said it above makes it sound like they are actually the same
stream.

cin - Standard input, file descriptor 0
cout - Standard output, file descriptor 1
cerr - Standard error, file descriptor 2
clog - Standard error, file descriptor 2

The difference between cerr and clog are that cerr is guaranteed to be
unbuffered, whereas clog may be buffered.

By default, cin takes input from the console, and cout and cerr send output
to the console.

On DOS, standard in and out can be redirected, but not standard error (Unix
shells and their clones for Windows support redirection of any of these).
