12 bool
13 ck_bitmap_next(ck_bitmap_t *bitmap, ck_bitmap_iterator_t iterator,
14 unsigned int *bit);
15
17 The ck_bitmap_next() function will increment the iterator object pointed
18 to by iterator to point to the next set bit in the bitmap. If
19 ck_bitmap_next() returns true then the pointer pointed to by bit is ini‐
20 tialized to the number of the current set bit pointed to by the iterator
21 object.
22
23 It is expected that iterator has been initialized using the
24 ck_bitmap_iterator_init(3) function.
25
27 If ck_bitmap_next() returns true then the object pointed to by bit con‐
28 tains a set bit. If ck_bitmap_next() returns false then value of the
29 object pointed to by bit is undefined.
30
32 Behavior is undefined if iterator or bitmap are uninitialized.
