CK_BITMAP_TEST(3)     DragonFly Library Functions Manual     CK_BITMAP_TEST(3)

NAME
     ck_bitmap_next - iterate to the next set bit in bitmap

LIBRARY
     Concurrency Kit (libck, -lck)

SYNOPSIS
     #include <ck_bitmap.h>

     bool
     ck_bitmap_next(ck_bitmap_t *bitmap, ck_bitmap_iterator_t iterator,
         unsigned int *bit);

DESCRIPTION
     The ck_bitmap_next() function will increment the iterator object pointed
     to by iterator to point to the next set bit in the bitmap. If
     ck_bitmap_next() returns true then the pointer pointed to by bit is
     initialized to the number of the current set bit pointed to by the
     iterator object.

     It is expected that iterator has been initialized using the
     ck_bitmap_iterator_init(3) function.

RETURN VALUES
     If ck_bitmap_next() returns true then the object pointed to by bit
     contains a set bit. If ck_bitmap_next() returns false then value of the
     object pointed to by bit is undefined.

ERRORS
     Behavior is undefined if iterator or bitmap are uninitialized.
