How to capture output from OutputDebugString?

NTDEV

Hello all,

I would like to read the messages that are output by
OutputDebugString. From my research, it looks like the messages are
written to a memory mapped region called DBWIN_BUFFER. I’ve tried
finding sample code that does this, but I can’t seem to find a good
example. Would anyone know where I could find a good example on how
to read from this buffer?

Thanks,
J

Or use Google for DBMON and/or DBWIN_BUFFER. There is a lot of info.
