Detailed Description

Internal header used by the foreign-function interface to OSFI-C++.

This file exposes an interface to the OSFI functions that can be called without C++ name mangling or other C++-specific features such as exception handling. It is not the OSFI-C interface, which resides in "OSFIC.h". It is intended as an intermediate layer to create bindings to OSFI-C++ from other languages; currently C and Fortran are supported through it.

    int osfi_confm_vector_##Tname##_copyall(const OSFI_VEC_T(Tname) *v, Ttype* arr, int length);

OSFI_DECL_VEC_GETTER_str

#define OSFI_DECL_VEC_GETTER_str	(		Tname,
			Ttype
	)

Value:

    bool osfi_confm_vector_##Tname##_copyall(const OSFI_VEC_T(Tname) *v, Ttype* strArr, int* itemSz, int* numItems);

OSFI_DECL_VEC_OPER

#define OSFI_DECL_VEC_OPER	(		Tname,
			Ttype,
			kind
	)

Value:

 \
    int osfi_confm_vector_##Tname##_numel(const OSFI_VEC_T(Tname) *v); \ \
    void osfi_confm_vector_##Tname##_destroy(OSFI_VEC_T(Tname) ** obj); \
    OSFI_DECL_VEC_GETTER_ ## kind(Tname, Ttype);

OSFI_DECL_VEC_T

#define OSFI_DECL_VEC_T	(		Tname,
			Ttype
	)

Value:

 \
        OSFI_FFI_DECL_PLACEHOLDER(OSFI_VEC_T(Tname))

OSFI_DECL_VECTOR

#define OSFI_DECL_VECTOR	(		Tname,
			Ttype,
			kind
	)

Value:

    OSFI_DECL_VEC_T(Tname, Ttype); \
    OSFI_DECL_VEC_OPER(Tname, Ttype, kind)

Declares an OSFI-managed vector type and its associated functions.

Parameters

Tname	the name for the type and its functions.
Ttype	the element type in the FFI.
kind	either simple or str, depending on the element type.

OSFI_FFI_DECL_PLACEHOLDER

#define OSFI_FFI_DECL_PLACEHOLDER

(

name

)

typedef struct CONCAT(name,_t) name

Declares an incomplete type with the given name, a placeholder to be used by the FFI API only in pointer form.

OSFI_FFI_NORETURN

#define OSFI_FFI_NORETURN   [[noreturn]]

Attribute to specify that a function never returns. Empty if unsupported

Typedef Documentation

OSFI_TimeValue

typedef struct OSFI_TimeValue_t OSFI_TimeValue

TimeValue object, in the FFI.
