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 *bmp);
       int bitmask_isallclear(const struct bitmask *bmp);

   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 bitmask_equal(const struct bitmask *bmp1, const bitmask *bmp2);
       int bitmask_subset(const struct bitmask *bmp1, const bitmask *bmp2);
       int bitmask_disjoint(const struct bitmask *bmp1, const bitmask *bmp2);
       int bitmask_intersects(const struct bitmask *bmp1, const bitmask *bmp2);

   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 *bmp1, const bitmask *bmp2, const bitmask *bmp3);
       struct bitmask *bitmask_or(struct bitmask *bmp1, const bitmask *bmp2, const bitmask *bmp3);
       struct bitmask *bitmask_eor(struct bitmask *bmp1, const bitmask *bmp2, const bitmask *bmp3);

   Iteration operators:
       int bitmask_first(const struct bitmask *bmp);
       unsigned int bitmask_next(const struct bitmask *bmp, unsigned int i);
       unsigned int bitmask_rel_to_abs_pos(const struct bitmask *bmp, unsigned int n);
       unsigned int bitmask_abs_to_rel_pos(const struct bitmask *bmp, unsigned int n);
       unsigned int bitmask_last(const struct bitmask *bmp);
