Function Documentation

bv_are_equal()

bool bv_are_equal	(	const unsigned char *	vec1,
		const unsigned char *	vec2,
		size_t	size1,
		size_t	size2
	)

Compares elements of two bitvectors.

Both vectors are expected to have same number of elements, i.e. , size1 must be equal to size2.

Definition at line 51 of file bitvector.cpp.

bv_check_mask()

bool bv_check_mask	(	const unsigned char *	vec1,
		const unsigned char *	vec2,
		size_t	size1,
		size_t	size2
	)

Return whether two vectors: vec1 and vec2 have common bits.

I.e. (vec1 & vec2) != 0.

Don't call this function directly, use BV_CHECK_MASK macro instead. Don't call this function with two different bitvectors.

Definition at line 31 of file bitvector.cpp.

bv_clr_all_from()

void bv_clr_all_from	(	unsigned char *	vec_to,
		const unsigned char *	vec_from,
		size_t	size_to,
		size_t	size_from
	)

Clear everything that is true in vec_from in vec_to.

Stuff that already is false in vec_to aren't touched.

Both vectors are expected to have same number of elements, i.e. , size1 must be equal to size2.

Don't call this function directly, use BV_CLR_ALL_FROM macro instead.

Definition at line 99 of file bitvector.cpp.

bv_set_all_from()

void bv_set_all_from	(	unsigned char *	vec_to,
		const unsigned char *	vec_from,
		size_t	size_to,
		size_t	size_from
	)

Set everything that is true in vec_from in vec_to.

Stuff that already is true in vec_to aren't touched. (Bitwise inclusive OR assignment)

Both vectors are expected to have same number of elements, i.e. , size1 must be equal to size2.

Don't call this function directly, use BV_SET_ALL_FROM macro instead.
