Function Documentation

◆ x_make_vector()

x_obj_t * x_make_vector	(	x_obj_t *	p_base,
		x_obj_flag_t	flags,
		x_int_t	length,
			...
	)

Allocate a VECTOR object holding the objects that follow.

The length is an INTEGER object of its own, as the length of a vector x-lang makes is, so the two are read the same way.

Parameters

p_base	Base (execution context).
flags	Object flags.
length	The number of elements.
...	The elements, `length` of them, each an `x_obj_t *`.

Returns: Newly allocated VECTOR object.

◆ x_type_vector_length()

x_obj_t * x_type_vector_length	(	x_obj_t *	p_base,
		x_obj_t *	p_args
	)

Type-system length handler for VECTOR objects.

Parameters

p_base	Base (execution context).
p_args	Argument list: (vector . ...).

Returns: The vector's length object.

◆ x_type_vector_register()

x_obj_t * x_type_vector_register	(	x_obj_t *	p_base,
		x_obj_t *	p_args
	)

Register (or retrieve) the VECTOR type in the type alist.

Calls x_type_struct_get() with the VECTOR name and struct constructor,

Parameters

p_base	Base (execution context).
p_args	Unused.

Returns: The registered VECTOR type object.

◆ x_type_vector_struct()

x_obj_t * x_type_vector_struct	(	x_obj_t *	p_base,
		x_obj_t *	p_args
	)

Build the VECTOR type struct descriptor.

Populates the name, the unit count and the length handler for the type system. With no save handler of its own the type takes the default, which writes the units the count declares: the length, then the elements, each a reference.

Parameters
