// Module Name: lspguid.cpp
|
|
//
|
|
// Description:
|
|
//
|
|
// This module defines the GUID under which the LSP's hidden dummy
|
|
// entry is to be installed under. This GUID must be hard coded in
|
|
// this file so that the DLL instance can find itself in the Winsock
|
|
// catalog. Once it finds the dummy hidden entry, it can then find
|
|
// the layered protocol entries belonging to the LSP (since these
|
|
// entries will reference the catalog ID of the hidden dummy entry).
|
|
//
|
|
// It is possible to create multiple LSPs by simply copying this project
|
|
// to another directory, changing the GUID in this file, and changing
|
|
// the DLL name. The LSP installer (instlsp.exe) can then install each
|
|
// LSP with the -d flag which is the full path to each LSP to install.
|
|
//
|
|
// A new export has been added: GetLspGuid. This allows the LSP installer
|
|
// to install an arbitrary LSP as long as it exports this function as the
|
|
// installer needs to find the GUID to install the hidden dummy entry
|
|
// with. The GUIDs for the layered protocol entries are generated on the
|
|
// fly.

// Function: GetLspGuid
|
|
//
|
|
// Description:
|
|
// This function is exported by the DLL and it returns the GUID under
|
|
// which the LSP (hidden) entry is to be installed. Note that this export
|
|
// is not required to write an LSP but it is here to make the installer code
|
|
// easier since the LSP DLL and the installer at least need to know the GUID
|
|
// of the hidden dummy entry of the LSP. Using this export allows the installer
|
|
// to query each LSP instance of its GUID so that it may install it.
