Implementing the Entry-Point Function

A database loader DLL must implement a standard entry-point function for Loadstub to call. The call to that entry-point function starts the DLL code that loads data into the Guide database. The entry-point function must be named EPG_DBLoad.

The prototype for this function is

ExitCodeList APIENTRY
EPG_DBLoad(int &argc, _TCHAR **argv, CdbDBEngine &db
    , PFNFORCEQUIT pfnForceQuit);

where the first two parameters are command-line parameters of the type you see in a main function of a standard C program. The next parameter is a reference to the database, and the final parameter is the address of the quit-processing callback function. This callback function takes no arguments and returns TRUE if the operating system is trying to shut down the loader, and FALSE otherwise.

Note  The sample loader Load.cpp contains an implementation of EPG_DBLoad. Thus, if you build your loader using the Load framework, you do not need to implement EPG_DBLoad.
