Module Name:

dbgtrace.hxx

|
|
|

|
|
Abstract:
|
||
|
|
|
||
|
|
Debug tracer routines. Tracer routines are used to
|
||
|
|
display a debugging message on entry and exit of
|
||
|
|
a subroutine call. Note this class relies on the
|
||
|
|
debug message class. A user must use and initialize
|
||
|
|
the debug messages for tracer to work.
