.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.
