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.)

Invocation:

GENPTR_type_FUNCTION(name)

Arguments:

name

The dummy argument.

Examples:

GENPTR_type_FUNCTION(name)

will expand as follows:

All systems:

Notes:

The dummy argument should have been declared with the type_FUNCTION macro.
