DbgPrint from WDK sample

I need to call DbgPrint or KdPrint function from WDK sample src\print\monitors\localmon

Please help with instructions

I've just added

#include <ntddk.h> in localmon.c file

and

DbgPrint("Some message"); in same file

and at compiling I've get next errors:

1>errors in directory c:\winddk\7600.16385.1\src\print\new2\monitors\localmon
1>c:\winddk\7600.16385.1\inc\api\ntdef.h(149) : error C2220: warning treated as

1>c:\winddk\7600.16385.1\inc\api\ntdef.h(973) : error C2011: '_LUID' : 'struct'

What i'm doing wrong?

Thanks

This is user-mode code. Use OutputDebugString instead and don't include ntddk.h at all. If you need to, write a little function as adapter to OutputDebugString as it does not take a formatting string etc. like its counterpart DbgPrint.

If you absolutely must use DbgPrint, it is also available from ntdll.dll, of course. So you could reach into that and import it from there (prototype can be found in wdm.h in the WDK). But I would prefer OutputDebugString in user-mode code.
