You apparently don't understand C++ enough.

The prototype given indicates that the function expects to be passed
two arguments, but does not need to reference them.  It is a
consequence of the ability to have *some* of the arguments unnamed as
placeholders (so that you don't get a warning about not using a named
parameter).  Consider:

	     int foo (char *a, int, int b) { }

The second parameter indicates that something *is* passed, and foo
*knows* about it, but doesn't use it.

Compare:

	int main() { }

This means that main doesn't expect any parameters.

	int main(int, char **) { }

This means that main expects parameters, but won't use them.
