Detailed Description

Macros to aid cross-language linkage between C/C++ and Fortran.

Macro Definition Documentation

◆ _CPFX

#define _CPFX

Defines the C++ linkage type on Windows.

◆ DOUBLE_FUNCTION

#define DOUBLE_FUNCTION	(	name,
		NAME
	)	F90_FUNCTION(double,name,NAME)

Macro for declaration for Fortran double functions in C/C++.

◆ F90_FUNCTION

#define F90_FUNCTION	(	type,
		name,
		NAME
	)	type _CPFX F90_NAME(name,NAME)

Macro for portable handling of linkage in mixed C/C++/F90 calls.

◆ f90_int

#define f90_int int

Integer type corresponding to the default Fortran integer kind.

◆ f90_int8

#define f90_int8 long

Integer type corresponding to the Fortran integer kind kindmodule::i8.

See also: kindModule.f90

◆ F90_NAME

#define F90_NAME	(	name,
		NAME
	)	name##_

Macro for portable handling of name conventions in mixed C/C++/Fortran.

Since there is no way(?) to translate a lowercase string into an uppercase string through preprocessor macros, we must specify both the lower- and uppercase version of the name.

◆ INTEGER_FUNCTION

#define INTEGER_FUNCTION	(	name,
		NAME
	)	F90_FUNCTION(f90_int,name,NAME)

Macro for declaration for Fortran integer functions in C/C++.

◆ PTR_FUNCTION

#define PTR_FUNCTION	(	name,
		NAME
	)	F90_FUNCTION(void*,name,NAME)

Macro for declaration for Fortran pointer functions in C/C++.

◆ ptr_int

#define ptr_int int

Integer type used in type casting to/from C/C++ pointers and Fortran.

See also: pointerkindmodule in FFrExtractorInterface.f90

◆ REAL_FUNCTION

#define REAL_FUNCTION	(	name,
		NAME
	)	F90_FUNCTION(float,name,NAME)

Macro for declaration for Fortran real functions in C/C++.

◆ SUBROUTINE

#define SUBROUTINE	(	name,
		NAME
	)	F90_FUNCTION(void,name,NAME)

Macro for declaration for Fortran subroutines in C/C++.
