WPP Tracing: Customizing DoTraceMessage.

NTFSD
1

Hi ALL:

I am trying to replace the DoTraceMessage API with my own, but I cannot even get my code to compile. Any help will be greatly appreciated.

I added the following to my source file:
RUN_WPP=$(SOURCES) -km -func:DebugTraceR((INDENT,LEVEL,Format,…))
DebugTraceR is defined as following:
void DebugTraceR(int INDENT, UInt64 LEVEL, char *Format, …)
The build fails with the following error:
error : (ParseSrcCallback)DebugTraceR requires ((args))
Thanks in advance,
Ilya.

Hi,

You shouldn’t be defining the tracing function yourself anywhere, it’s
automatically generated for you.

AFAIK the tracing templates supplied in the DDK don’t provide this level of
customization to the tracing message. I think that if you want to change the
format of the output (such as adding an indent) it’s going to require that
you create your own WPP templates, which is probably more trouble than it’s
worth. You can browse through the \bin\wppconfig directory of the DDK to get
an idea as to what you’d be getting yourself into.

No this is the standard way to tell WPP your program has a function
similar to DoTraceMessage and you want WPP to use that to generate
tracing.

It is basically correct, but you don’t need to define DebugTraceR

Remove this
void DebugTraceR(int INDENT, UInt64 LEVEL, char *Format, …)

To a header file that you don’t include when building with WPP enabled.

WPP may be seeing the function definition and treating it as a call.

Also are all of your calls to DebugTraceR really using double braces
(()) if not remove them from the -func call.
