CK_BITMAP_TEST(3) | 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¶
Theck_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¶
Ifck_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.SEE ALSO¶
