Function PythonService_main

* * * Generic Service Host implementation - handles command-line args, * uses the registry to work out what Python classes to load, etc. * This section could be split into the EXE. * * *************************************************************************/ FUNCTION: PythonService_main PURPOSE: entrypoint for our generic PythonService host PARAMETERS: argc - number of command line argu

//    the service has stopped, so exit.

	// If only one service is hosted, then it is no real problem - our dispatch
	// table has a single entry, and this must be our service (and indeed
	// Windows doesn't care - it ignores the service name in the dispatch table
	// if SERVICE_WIN32_OWN_PROCESS is set.
	// However, if we want to host multiple services, we have a problem.
	// For now, the solution is to not support multiple services via this
	// generic PythonService.exe.  However, py2exe etc is free to register
	// multiple services (and we don't care how it find out the service names)
	// Later, we could add support to the service registration code so that
	// the service names are always passed on the command-line (-services=)
	// (This is also the reason "-debug" requires the service name on the
	// command-line.)
