Re: shared library entry point

	[it is... but you look so good :)]

->I have been looking for some documentation on initialization

	I don't think this concept exists on Unix systems.
	Actually it is not needed at all - and this reveals
	a major Windows design problem : a library is not
	an executable file. A library is a library. Nothing
	more.

	Actually, to do what you want, you'll probably have
	to load the libary with dlopen() and provide your
	own interface to the library - just a small wrapper,
	something like

	void *
	my_dlopen(path,mode)
	const char *path;
	int mode;
	{
		void		*hmodule;
		my_init_func_t  func;

		hmodule = dlopen(path,mode);
		func = (my_init_func_t)dlsym(hmodule,"my_init_func");
		func(params);
		return (hmodule);
	}
	
	[of course, you must check return codes]
		
	Hope this helps, regards.
