GENPTR_type_FUNCTION
Generate a pointer to a FUNCTION argument
Description:
Ensure that there exists a pointer of the
appropriate type to the FORTRAN FUNCTION that has been passed as an actual argument
from FORTRAN to a C routine. Since FORTRAN usually passes arguments by reference,
the pointer is commonly available directly from the argument list, so this macro is null.
(type not LOCATOR.)
