Unless you are using C++, you need to declare this as
	struct text_info *foo;

> gettextinfo (*foo);

My guess is that you want to call function gettextinfo like so:
	gettextinfo(foo);

This way, you pass the pointer, so that the function can pass information
back using a statement such as "foo->screenheight = 25;"
