Detailed Description

Macros for accessing data in the QFO address space.

Macro Definition Documentation

#define QFO_FLOAT	(		q,
			s,
			o
	)

Access a float variable in the object file.

Can be assigned to.

QC type:

float

Parameters

q	pointer to qfo_t struct
s	space index
o	offset into object file data space

Returns

float lvalue

#define QFO_FUNCTION	(		q,
			s,
			o
	)

Access a function variable in the object file.

Can be assigned to.

QC type:

void ()

Parameters

q	pointer to qfo_t struct
s	space index
o	offset into object file data space

Returns

func_t lvalue

#define QFO_GETSTR	(		q,
			s
	)

Retrieve a string from the object file, converting it to a C string.

Parameters

q	pointer to qfo_t struct
s	space index
s	offset into object file string space

Returns

(char *)

#define QFO_GSTRING	(		q,
			s,
			o
	)

Access a string global, converting it to a C string.

Parameters

q	pointer to qfo_t struct
s	space index
o	offset into object file data space

Returns

(char *)

#define QFO_INT	(		q,
			s,
			o
	)

Access a integer variable in the object file.

Can be assigned to.

QC type:

integer

Parameters

q	pointer to qfo_t struct
s	space index
o	offset into object file data space

Returns

int lvalue

#define QFO_POINTER	(		q,
			s,
			t,
			o
	)

Access a block of memory in the object file as a C struct.

QC type:

void []

Parameters

q	pointer to qfo_t struct
s	space index
t	C type of the structure
o	offset into object file data space

Returns

C pointer to the struct at space:offset

#define QFO_STATEMENT	(		q,
			s
	)		((q)->spaces[qfo_code_space].d.code + (s))

#define QFO_STRING	(		q,
			s,
			o
	)

Access a string index variable in the object file.

Can be assigned to.

QC type:

string

Parameters

q	pointer to qfo_t struct
s	space index
o	offset into object file data space

Returns

string_t lvalue

#define QFO_STRUCT	(		q,
			s,
			t,
			o
	)

Access a structure variable in the object file.

Can be assigned to.

QC type:

void [](?)

Parameters

q	pointer to qfo_t struct
s	space index
t	C type of the structure
o	offset into object file data space

Returns

structure lvalue. use & to make a pointer of the appropriate type.

#define QFO_TYPE	(		q,
			t
	)

Value:

((qfot_type_t *) (char *) \
                             ((q)->spaces[qfo_type_space].d.data + (t)))

#define QFO_TYPEMETA	(		q,
			t
	)		QFO_INT (q, qfo_type_space, (t) + 0)

#define QFO_TYPESTR	(		q,
			t
	)

Retrieve a type string from the object file, converting it to a C string.

Parameters

q	pointer to qfo_t struct
t	offset to type encoding

Returns

(char *)

Note

Assumes standard space order.

#define QFO_TYPETYPE	(		q,
			t
	)		QFO_INT (q, qfo_type_space, (t) + 3)
