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
main.c(26) : error C4013: 'WPP_FLAG_LEVEL_ENABLED' undefined; assuming extern returning int
main.c(26) : error C2065: 'DBGF_INIT' : undeclared identifier
main.c(26) : error C4013: 'WPP_FLAG_LEVEL_LOGGER' undefined; assuming extern returning int
main.c(26) : error C2143: syntax error : missing ')' before 'constant'

Do I need to define those?
