Module Name:
|
||
|
|
|
||
|
|
reftrace.h
|
||
|
|
|
||
|
|
Abstract:
|
||
|
|
|
||
|
|
This module contains public declarations and definitions for tracing
|
||
|
|
and debugging reference count problems. This module uses the generic
|
||
|
|
TRACE_LOG facility in tracelog.h.
|
||
|
|
|
||
|
|
Ref count trace logs can be dumped via the !inetdbg.ref command
|
||
|
|
in either NTSD or CDB.
