.Dt CK_BITMAP_TEST 3
.Sh NAME
.Nm ck_bitmap_next
.Nd iterate to the next set bit in bitmap
.Sh LIBRARY
Concurrency Kit (libck, \-lck)
.Sh SYNOPSIS
.In ck_bitmap.h
.Ft bool
.Fn ck_bitmap_next "ck_bitmap_t *bitmap" "ck_bitmap_iterator_t iterator" "unsigned int *bit"
.Sh DESCRIPTION
The
.Fn ck_bitmap_next
function will increment the iterator object pointed to by
.Fa iterator
to point to the next set bit in the bitmap. If
.Fn ck_bitmap_next
returns
.Dv true
then the pointer pointed to by
.Fa bit
is initialized to the number of the current set bit pointed to by the
.Fa iterator
object.
.Pp
It is expected that
.Fa iterator
has been initialized using the
.Xr ck_bitmap_iterator_init 3
function.
.Sh RETURN VALUES
If
.Fn ck_bitmap_next
returns
.Dv true
then the object pointed to by
.Fa bit
contains a set bit. If
.Fn ck_bitmap_next
returns
.Dv false
then value of the object pointed to by
.Fa bit
is undefined.
.Sh ERRORS
Behavior is undefined if
.Fa iterator
or
.Fa bitmap
are uninitialized.
