Redirecting driver errors to a file ?

This is probably more of a General Programming question. Have a look at This article, and see if that helps. It's in MDX, but it should translate to C++ without much difficulty.

Thx for the answer. I didn't read it in detail, but let me explain a little better my problem :

I'd like to redirect messages generated by the DirectX runtime. Not by my code. Those messages are stuff like :

"D3DX: Matrix should be 16-byte aligned for better performance"

And I don't have any control on that. It's not inside my code, there is no function to desactivate that, other than the DirectX configuration panel.

Yea, go back and read it - it is exactly what you want. From within a process, you can capture all messages sent to OutputDebugStream() on its behalf. This will let you capture these messages and do whatever you want with it.

I should do this sometime too, it would be nice to have.

Odds are the error messages are being sent to the standard error stream. Redirect that.

In C: stderr = freopen(stderr, stuff goes here)
In C++: std::cerr.rdbuf( stuff goes here )

I thought that stderr ended up on stdout? Or it did the last time I tried it with VC6. Although it's entirely possible I was doing something wrong...

They both end up on the console by default, but they are two separate streams that can be independently redirected.
