This would work for a combination of FLAGS and LEVEL not for a simple LEVEL instead of FLAGS, though note that even here there is a comma missing from the end of WPP_FLAG_LEVEL_LOGGER.
#define WPP_FLAG_LEVEL_LOGGER(ulFlags, ulLevel)?? WPP_LEVEL_LOGGER(ulFlags),
If you simply want to do LEVEL instead of flags there is a trick that works quite nicely.
Do something like the following (note the use of a dummy flag so WPP can find the data structure)
#define WPP_CONTROL_GUIDS \
??? WPP_DEFINE_CONTROL_GUID(CtlGuid,(a044090f,3d9d,48cf,b7ee,9fb114702dc1),? \
??? WPP_DEFINE_BIT(DUMMY))
#define WPP_LEVEL_LOGGER(lvl) (WPP_CONTROL(WPP_BIT_ ## DUMMY).Logger),
#define WPP_LEVEL_ENABLED(lvl) WPP_CONTROL(WPP_BIT_ ## DUMMY).Level >= lvl

Subject: [ntdev] RE: WPP with LEVEL tracing.
Adding the following to common.h file solved the compile problem. But I have no idea if this would work. Any comments if the following make sense…
?
#define WPP_FLAG_LEVEL_LOGGER(ulFlags, ulLevel)?? WPP_LEVEL_LOGGER(ulFlags),
?
#define WPP_FLAG_LEVEL_ENABLED(ulFlags, ulLevel) ??? \
??? (WPP_LEVEL_ENABLED(ulFlags) && WPP_CONTROL(WPP_BIT_##ulFlags).Level <= ulLevel)
?
?
Looks like needs more digging for now…

I tried building a test project to use WPP. It compiles fine if I use DoTraceMessage. But if use either LEVEL tracing feature or if I use a custom function build fails with the following errors. The driver entry does not do anything please do not complain about that. I am still trying to make the simple project build not run…
?
Any help is appreciated.

Compiling - main.c for i386

Do I need to define those?
