SYNOPSIS
#include <bitmask.h>
cc ... -lbitmask
Allocate and free ‘struct bitmask *‘:
struct bitmask
*bitmask_alloc(unsigned int
nbits
);
void bitmask_free(struct bitmask *
bmp
);
Display and parse ascii string representations:
int
bitmask_displayhex(char *
buf
, int
len
, const
struct bitmask *
bmp
);
int bitmask_displaylist(char *
buf
, int
len
,
const struct bitmask *
bmp
);
int bitmask_parsehex(const char *
buf
, struct bitmask
*
bmp
);
int bitmask_parselist(const char *
buf
, struct bitmask
*
bmp
);
Basic initialization operations:
struct bitmask
*bitmask_copy(struct bitmask *
bmp1
, const bitmask
*
bmp2
);
struct bitmask *bitmask_setall(struct bitmask *
bmp
);
struct bitmask *bitmask_clearall(struct bitmask

bmp
);
Interface to kernel sched_{set,get}affinity system calls:
unsigned int
bitmask_nbytes(struct bitmask *
bmp
);
unsigned long *bitmask_mask(struct bitmask *
bmp
);
Unary numeric queries:
unsigned int
bitmask_nbits(const struct bitmask *
bmp
);
unsigned int bitmask_weight(const struct bitmask

bmp
);
Unary Boolean queries:
int
bitmask_isbitset(const struct bitmask *
bmp
, unsigned
int
i
);
int bitmask_isbitclear(const struct bitmask *
bmp
,
unsigned int
i
);
int bitmask_isallset(const struct bitmask *

);
int bitmask_isallclear(const struct bitmask

Single bit operations:
struct bitmask
*bitmask_setbit(struct bitmask *
bmp
, unsigned int
i
);
struct bitmask *bitmask_clearbit(struct bitmask *
bmp
,
unsigned int
i
);
Binary Boolean operations: bmp1 op? bmp2:
int

);
int bitmask_subset(const struct bitmask *
bmp1

int bitmask_disjoint(const struct bitmask *
bmp1
,
const bitmask *

int bitmask_intersects(const struct bitmask *
bmp1
,
const bitmask *

Range operations:
struct bitmask
*bitmask_setrange(struct bitmask *
bmp
, unsigned int
i
, unsigned int
j
);
struct bitmask *bitmask_clearrange(struct bitmask
*
bmp
, unsigned int
i
, unsigned int
j
);
struct bitmask *bitmask_keeprange(struct bitmask
*
bmp
, unsigned int
i
, unsigned int
j
);
Unary operations:
struct bitmask
*bitmask_complement(struct bitmask *
bmp1
, const
bitmask *
bmp2
);
struct bitmask *bitmask_shiftright(struct bitmask
*
bmp1
, const bitmask *
bmp2
, unsigned int
n
);
struct bitmask *bitmask_shiftleft(struct bitmask
*
bmp1
, const bitmask *
bmp2
, unsigned int
n
);
Binary operations:
struct bitmask
*bitmask_and(struct bitmask *
bmp1
, const bitmask
*
bmp2
, const bitmask *
bmp3
);
struct bitmask *bitmask_andnot(struct bitmask *

);
struct bitmask *bitmask_eor(struct bitmask *

Iteration operators:
int
bitmask_first(const struct bitmask *

);
unsigned int bitmask_next(const struct bitmask *

,
unsigned int

);
unsigned int bitmask_rel_to_abs_pos(const struct bitmask
