Data Structures
struct	fixed_bitset_t
	Base type for a fixed-size bitset. More...

Macros
#define	fixed_bitset_type(N)
	Macro used to define a fixed-size bitset of a given size.
#define	fixed_bitset_sizeof_for(N)
#define	fixed_bitset_with_fill(type, N, fill)
	Macro used to create a bitset with all bits set to a value.
#define	fixed_bitset_init(ptr, type, N, fill)
	Initialize a bitset.

Functions
static uint	fixed_bitset_size (const fixed_bitset_t *bitset)
	Get the size of the bitset.
static uint	fixed_bitset_word_size (const fixed_bitset_t *bitset)
	Get the size of the bitset in words.
static void	check_fixed_bitset (__unused const fixed_bitset_t *bitset)
	Check that the bitset is valid.
static fixed_bitset_t *	fixed_bitset_write_word (fixed_bitset_t *bitset, uint word_num, uint32_t value)
	Write a word in the bitset.
static uint32_t	fixed_bitset_read_word (const fixed_bitset_t *bitset, uint word_num)
	Read a word in the bitset.

	Set all bits in the bitset.
fixed_bitset_t *	fixed_bitset_flip_all (fixed_bitset_t *bitset)
	Flip all bits in the bitset.
bool	fixed_bitset_is_empty (fixed_bitset_t *bitset)
	Determine if bitset is empty.
static fixed_bitset_t *	fixed_bitset_set (fixed_bitset_t *bitset, uint bit_index)
	Set a single bit in the bitset.
static fixed_bitset_t *	fixed_bitset_clear (fixed_bitset_t *bitset, uint bit_index)
	Clear a single bit in the bitset.
static fixed_bitset_t *	fixed_bitset_flip (fixed_bitset_t *bitset, uint bit_index)
