Usage

Trace macros work like printf() functions. The input to the trace functions must be surrounded by a two sets of parenthesis.

TINFO(("Trace output of a %s","string"));

A user defined Trace Function can be set with:

• SetLevelTraceFunction()

The user trace function can also call back to the default console trace function:

• Default_TraceLevelFunction(NULL,Level,Format,Args);
