Function Documentation

cu_bool_t cucon_bitarray_slice_at	(	cucon_bitarray_slice_t	sl,
		size_t	i
	)

Read bit number i of sl.

void cucon_bitarray_slice_copy	(	cucon_bitarray_slice_t	dst,
		cucon_bitarray_slice_t	src
	)

Copy src to dst.

Precondition:

src must be at least as long as dst.

void cucon_bitarray_slice_copy_bool1f	(	cu_bool1f_t	f,
		cucon_bitarray_slice_t	dst,
		cucon_bitarray_slice_t	src0
	)

Copy the image of the slice src0 under f to dst.

Precondition:

src0 must be at least as long as dst.

void cucon_bitarray_slice_copy_bool2f	(	cu_bool2f_t	f,
		cucon_bitarray_slice_t	dst,
		cucon_bitarray_slice_t	src0,
		cucon_bitarray_slice_t	src1
	)

Copy the image under f of zipped pairs from src0 and src1 to dst.

Precondition:

src0 and src1 must be at least as long as dst.

void cucon_bitarray_slice_fill	(	cucon_bitarray_slice_t	sl,
		cu_bool_t	v
	)

Fill sl with the constant value v.

void cucon_bitarray_slice_init	(	cucon_bitarray_slice_t	sl,
		cucon_bitarray_t	ba,
		size_t	start_index,
		size_t	end_index
	)

Initialise sl as a slice of ba covering the range from start_index up to end_index.

void cucon_bitarray_slice_init_copy	(	cucon_bitarray_slice_t	sl,
		cucon_bitarray_slice_t	sl_src
	)

Initialise sl to the same slice as sl_src.

void cucon_bitarray_slice_init_sub	(	cucon_bitarray_slice_t	sl,
		cucon_bitarray_slice_t	sl_src,
		size_t	start_index,
		size_t	end_index
	)

Initialise sl as a slice of the same array from which sl_src was constructed and covering start_index up to end_index relative to the start of sl_src.

void cucon_bitarray_slice_set_at	(	cucon_bitarray_slice_t	sl,
		size_t	i,
		cu_bool_t	v
	)

Assign v to bit i of sl.

size_t cucon_bitarray_slice_size

(

cucon_bitarray_slice_t

sl

)

The number of bits covered by sl.

void cucon_bitarray_slice_update_bool1f	(	cu_bool1f_t	f,
		cucon_bitarray_slice_t	dst
	)

Replace each bit x of dst with cu_bool1f_apply(f, x).

void cucon_bitarray_slice_update_bool2f	(	cu_bool2f_t	f,
		cucon_bitarray_slice_t	dst,
		cucon_bitarray_slice_t	src1
	)

Replace each bit x of dst with cu_bool2f_apply(f, x, y), where y is the element of src1 at respective positions.

cu_word_t cucon_bitarray_slice_word_at	(	cucon_bitarray_slice_t	sl,
		size_t	i
	)

Return sizeof(cu_word_t)*8 bits from sl starting at i in the form of a cu_word_t. This is mostly useful to implement higher level functions like bitwise operations.
