Macro Definition Documentation

#define QFOSTR	(		q,
			s
	)		QFO_GETSTR (q, s)

#define QFOTYPE

(

t

)

Value:

((qfot_type_t *) (char *) \
                         (qfo_type_defs->d.data + (t)))

#define REF

(

r

)

(work->spaces[(r)->space].defs + (r)->def)

Retreive a def from a defref.

Parameters

r	The defref pointing to the def (defref_t *).

Returns

A pointer to the def (qfo_def_t *).

#define WORKSTR

(

s

)

QFOSTR (work, s)

#define WORKTYPE

(

t

)

Value:

((qfot_type_t *) (char *) \
                         (work_type_data->data + (t)))

Typedef Documentation

typedef struct builtin_sym_s builtin_sym_t

typedef struct defref_s defref_t

Safe handling of defs in hash tables and other containers.

As defs are stored in dynamic arrays, storing pointers to the defs is a recipe for disaster when using realloc(). By storing the address of the pointer to the array and the index into that that array, realloc is allowed to do its magic.

typedef struct path_s path_t

typedef int(* space_func)(qfo_t *qfo, qfo_mspace_t *space, int pass)

Function Documentation

void linker_add_def	(	const char *	name,
		type_t *	type,
		unsigned	flags,
		void *	val
	)

int linker_add_lib

(

const char *

libname

)

int linker_add_object_file

(

const char *

filename

)

void linker_add_path

(

const char *

path

)

int linker_add_qfo

(

qfo_t *

qfo

)

int linker_add_string

(

const char *

str

)

Add a string to the working qfo string pool.

If the string is already in the string pool, the already existing string index will be returned instead of adding a second copy of the string.

The strings space in the working qfo is kept up to date.

Parameters

str	The string to add.

Returns

The string offset in the working qfo string pool.

void linker_begin

(

void

)

Initialize the linker state.

qfo_def_t* linker_find_def

(

const char *

name

)

qfo_t* linker_finish

(

void

)
