// Descr iption:
//
//　　This sample illustrates how to develop a layered service provider that is
//　　capable of counting all bytes transmitted through an IP socket. The application
//　　reports when sockets are created and reports how many bytes were sent and
//　　received when a socket closes. The results are reported using the OutputDebugString
//　　API which will allow you to intercept the I/O by using a debugger such as cdb.exe
//　　or you can monitor the I/O using dbmon.exe.
//
//　　This file contains the 30 SPI functions you are required to implement in a
//　　service provider. It also contains the two functions that must be exported
//　　from the DLL module DllMain and WSPStartup.
