In the context of the problem above.  The function names in a
c++ program are converted- "mangled" in a way that enables the linker
to recognize weather it's a global fuction or class method, the
return type and paramters passed, to facilitate the overloading that
C++ is capable of. C funtions dont need all of that stuff so the
names are not mangled the same way. 

Someday I'll learn to spell weather <sic>
