GENPTR_type_ARRAY
- Generate a pointer to an array argument
- Description:
- Ensure that there exists a pointer of the appropriate type to the array
that has been passed as an actual argument to the 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.)
- Invocation:
- GENPTR_type_ARRAY(arg)
- Arguments:

arg
-
The dummy argument.
