All Rights Reserved. // // 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. // #include "lspdef.h" #include // // This is the hardcoded guid for our dummy (hidden) catalog entry // GUID gProviderGuid = { //c5fabbd0-9736-11d1-937f-00c04fad860d 0xc5fabbd0, 0x9736, 0x11d1, {0x93, 0x7f, 0x00, 0xc0, 0x4f, 0xad, 0x86, 0x0d} }; // // 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. // void WSPAPI GetLspGuid( LPGUID lpGuid ) { memcpy( lpGuid, &gProviderGuid, sizeof( GUID ) ); }
