Module Name:

    SimpleProvider.cpp

Abstract:

    Simple ETW provider sample for Windows 7 SDK.
    Demonstrates how to easily create a ETW provider using the macros generated by MC (Message Compiler).

Environment:

    User mode only.

//
// Include header file generated by MC (message compiler) containing support code for logging. The file is 
// generated based on the event definitions in the instrumentation manifest. The file defines macros for each 
// event defined in the manifest and hides calls to ETW Eventing APIs - making the developer's life way easier.
// Please refer to the ReadMe.txt to see the full script used for generating this file.

Routine Description:

    main() routine.
    Calls the macros defined in the generated code (SimpleProviderEvents.h) to log Integers, Floats, Boolean,
    UnicodeString and Guid.

Arguments:

    None.

Return Value:

   STATUS_SUCCESS if successful
   STATUS_UNSUCCESSFUL  otherwise
