Copyright (c) 1997-2000 Microsoft Corporation
Module Name:
tracedmp.c
Abstract:
Sample trace consumer program. Converts binary
Event Trace Log (ETL) to CSV format
// end_sdk
Author:
Jee Fung Pang (jeepang) 03-Dec-1997
Revision History:
Corey Morgan (coreym) 24-May-2000 Added MOF version support
Insung Park (insungp) 16-Jan-2001
tracedmp no longer uses MOF data file. All the layout information
comes from the WBEM namespace. Also added support for float numbers.
Also added comments for all the functions.

/*++
Routine Description:
Constructs a linked list with the information read from the WBEM
namespace, given the WBEM pointer to the version subtree. It enumerates
through all type classes in WBEM, and constructs MOF_INFOs for all of
them (for caching purpose). Meanwhile, it looks for the event layout
that mathces the passed event, and returns the pointer to the matching
MOF_INFO at the end.
Arguments:
pTraceSubClasses - WBEM pointer to the version subtree.
Guid - GUID of the passed event.
nVersion - version of the passed event.
nLevel - level of the passed event.
nType - type of the passed event.
Return Value:
Pointer to MOF_INFO corresponding to the passed event.
If the right type is not found, it returns the pointer to
the generic MOF_INFO for the event version.
