Yes, leading underscores are a (hidden) C convention.
It sounds like you compiled the library as a C library, and are using
it in a CPP program.
So telling the compiler that the function is a C function will do the
trick.
	extern "C" {	void MyFunctionName(void); };

Or
	extern "C" {
#include	"MyLibrary.h"
	};

Though many of the regulars would rather see the extern inside the
header file.
