Function Documentation

x_make_int()

x_obj_t * x_make_int	(	x_obj_t *	p_base,
		x_obj_flag_t	flags,
		x_int_t	i
	)

Allocate a heap integer object with value i.

Allocate a heap integer object with a given value.

Builds a stack-based argument list and delegates to x_type_int_make.

Parameters

p_base	x_obj_t* – Base (execution context)
flags	x_obj_flag_t – Object flags
i	x_int_t – Integer value

Returns

x_obj_t* – New heap-allocated integer object

x_type_int_make()

x_obj_t * x_type_int_make	(	x_obj_t *	p_base,
		x_obj_t *	p_args
	)

Type-system make callback for integer.

Type-system make callback for integer objects.

Extracts the integer value and optional flags from p_args, then allocates a heap object via x_obj_make.

Parameters

p_base	x_obj_t* – Base (execution context)
p_args	x_obj_t* – (int-value . (flags | nil))

Returns

x_obj_t* – New heap-allocated integer object

x_type_int_register()

x_obj_t * x_type_int_register	(	x_obj_t *	p_base,
		x_obj_t *	p_args
	)

Register (or retrieve) the integer type struct on p_base.

Register or retrieve the integer type on the base context.

Parameters

p_base	x_obj_t* – Base (execution context)
p_args	x_obj_t* – Unused

Returns

x_obj_t* – Registered type object

x_type_int_struct()

x_obj_t * x_type_int_struct	(	x_obj_t *	p_base,
		x_obj_t *	p_args
	)

Build the integer type descriptor struct.
