Availability:C-language interface function

bool PL_is_initialised(int *argc, char ***argv)

Test whether the Prolog engine is already initialised. Returns FALSE if Prolog is not initialised and TRUE otherwise. If the engine is initialised and argc is not NULL, the argument count used with PL_initialise() is stored in argc. Same for the argument vector argv.
