overloading as a member function

here is what i'm doing:
i tried compiling that because i was so confident it was right, and devcpp gives me:
"ISO C++ forbids declaration of `ostream' with no type"
"`ostream' is neither function nor member function; cannot be declared friend"
"expected `;' before '&' token"
so i checked my old "problem solving using c++" textbook and it says that is the correct way to do it, then i checked online and this is also how it was done. has the way to do this changed since all those sources were printed or am i doing something wrong that i just can't see?
thanks!
Off the top of my head:
Should be:
friend std::ostream& operator<<(std::ostream& outs, const point_type& outstuff);
I'm assuming you have <iostream> included at the top of pointclass.h?

... doh!
and yet again the simple stupid little things trip me up. i did have that extra "std::" but i forgot to type it in here (should have just copied and pasted), i also forgot to put in the "#include "pointclass.h" " include in the op. however, your second suggestion fixed it. and i thank you very much for helping me correct one of my stupid little brain malfunctions. :)
