Function Documentation

struct starpu_bitmap * starpu_bitmap_create ( void  )

create a empty starpu_bitmap

void starpu_bitmap_destroy ( struct starpu_bitmap *  b)

free a starpu_bitmap

void starpu_bitmap_set ( struct starpu_bitmap *  b,
int  e 
)

set bit e in b

void starpu_bitmap_unset ( struct starpu_bitmap *  b,
int  e 
)

unset bit e in b

void starpu_bitmap_unset_all ( struct starpu_bitmap *  b)

unset all bits in b

int starpu_bitmap_get ( struct starpu_bitmap *  b,
int  e 
)

return true iff bit e is set in b

void starpu_bitmap_unset_and ( struct starpu_bitmap *  a,
struct starpu_bitmap *  b,
struct starpu_bitmap *  c 
)

Basically compute starpu_bitmap_unset_all(a) ; a = b & c;

void starpu_bitmap_or ( struct starpu_bitmap *  a,
struct starpu_bitmap *  b 
)

Basically compute a |= b

int starpu_bitmap_and_get ( struct starpu_bitmap *  b1,
struct starpu_bitmap *  b2,
int  e 
)

return 1 iff e set in b1 AND e set in b2

int starpu_bitmap_cardinal ( struct starpu_bitmap *  b)

return the number of set bits in b

int starpu_bitmap_first ( struct starpu_bitmap *  b)

return the index of first set bit of b, -1 if none

int starpu_bitmap_last ( struct starpu_bitmap *  b)

return the position of the last set bit of b, -1 if none

int starpu_bitmap_next ( struct starpu_bitmap *  b,
int  e 
)

return the position of set bit right after e in b, -1 if none

int starpu_bitmap_has_next ( struct starpu_bitmap *  b,
int  e 
)
