No. export is correct ;)

It is used when you implement a template function in some source file
and want to use it in another. example:

---- templ.cc ----
#include "templ.h"

export void template <class C> PrintIt (C Parameter)
{
	cout << C;
}
------------------

---- templ.h -----
void template <class C> PrintIt (C Parameter);
------------------

---- main.cc -----
#include "templ.h"

int main (void)
{
	PrintIt (42);
	PrintIt ("Hello World");

	return 0;
}
------------------

without the "export" the linker wonīt find a "PrintIt (int)" and
"PrintIt (char *)" when linking main.o
