// Define a standard DllMain() function for Win32 plugin DLLs.
// Note: You haven't to delete or comment out this function for other platforms.
// SPL automatically detects the current platform and removes unused/unwanted code
// behind the macros.
//
SPL_DEFINE_PLUGIN_DLLMAIN();

//
// Implement default methods that we don't use in this example.
//
SPL_IMPLEMENT_PLUGIN_INITIALIZE();
SPL_IMPLEMENT_PLUGIN_SHUTDOWN();

//
// Implement a simple run method.
//
SPL_PLUGIN_API bool SPL_RUN_NAME_CODE( slcPluginArgs* a_pPluginArgs )
{
	return true;
}

//
// Sometimes a plugin comes without documentation, so what to do if you want
// to use it? If you're lucky, the programmer of this plugin has provided you
// with the needed arguments in the slcPluginInfo() structure, so all you have to
// do is to use and interprete this arguments in your program.
//
// If you're writing your own plugin, the best place for providing the structure
// with argument infos is the "splGetInfo" method. Let's take a look how we did this:
//
SPL_PLUGIN_API slcPluginInfo* SPL_GETINFO_NAME_CODE( void )
{
	SPL_SET_PLUGIN_INIT_ARGUMENT( "szFirstName", "First name" );
	SPL_SET_PLUGIN_INIT_ARGUMENT( "szLastName", "Last name" );

	SPL_SET_PLUGIN_RUN_ARGUMENT( "szTextToPrint", "Some nice text to print" );

	SPL_SET_PLUGIN_SHUTDOWN_ARGUMENT( "szShutdownText", "That's the folks!" );

	return &g_pluginInfo;
}

I was born in 1982 near Stuttgart / Germany and began my first steps in programming computers at the age of only nine years on an old Commodore CBM 7072. In 2002 I finished my education as IT specialist for software engineering and did my civillian service afterwards. Currently I'm working as leader of the software division in a bigger company located in south west Germany, mainly on software development and research projects for multimedia terminals and user recognition/verification systems.
