Redirect perror to file

[vinaynaikwad]

Hi,

I want to redirect the output of perror to a file. What is the best way to do that?

[kbw]

It writes to stderr. To redirect stderr to a file from a Bourne Shell derivative:

prog 2> errors.out

[vinaynaikwad]

You mean I can use this statement in a C++ program?

[theranga]

wouldn't you want to do something like this?

// Redirect it
freopen("error.out","w",stderr);

the main problem with this is that you can't 're-redirect' the stream back to the command line

[kbw]

You're asking the wrong question.

Use strerror to write the text to a buffer, then you do what you like with it.
