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.
