35 * Definition of macros and symbols to control trace generation.  Define
36 * the symbol NTRACE at compile time to remove all trace code.
37 *
38 * Conventions for assigning trace levels:
39 *   - Trace levels are always non-negative.
40 *   - Larger trace levels produce more trace output
41 *   - Trace level == 0 produces no output.
42 *   - Trace level == 1 produces one line of output for the operation
43 *     being traced, usually just a description of what is being called
44 *     and its arguments.
45 *   - Trace level >= 10 are for testing only; they are disabled
46 *     in the product code (controlled by VERBOSETRACE define).

382/* Routine entry/exit tracing:
383
384   In C code, place the macro ENTER(level) at the point of the first
385   executable statement of the routine.  This will generate a call to
386   cxiTraceEntry that will trace the call by function name and source line
387   if TRACE_ENTEREXIT is set high enough.  Optionally, place the macro
388   EXIT(level) at exits from the routine.
389
390   In C++ code, place the macro ENTER(level) as the first declaration in
391   the routine.  This will create an object of type EntryExitTracer,
392   whose constructor will call cxiTraceEntry to trace routine entry, and
393   whose destructor will call cxiTraceExit to trace routine exit.  The
394   EXIT macro may appear, but will be ignored.
395
396   The trace levels that appear in the ENTER and EXIT macros are interpreted
397   relative to a base trace level.  Setting the TRACE_ENTEREXIT level <
398   BASE_ENTEREXIT_LEVEL disables all enter/exit tracing.  To see enter/exit
399   traces from daemon code, set the TRACE_ENTEREXIT level to at least
400   BASE_ENTEREXIT_LEVEL+DAEMON_ENTEREXIT_TRACING.
401
402   Kernel stack depth checking is only supported on Linux, since we do
403   not know how to compute the current stack usage on AIX.
