.Dt CK_HT_NEXT 3
.Sh NAME
.Nm ck_ht_next
.Nd iterate to next entry in hash table
.Sh LIBRARY
Concurrency Kit (libck, \-lck)
.Sh SYNOPSIS
.In ck_ht.h
.Ft bool
.Fn ck_ht_next "ck_ht_t *ht" "ck_ht_iterator_t *iterator" "ck_ht_entry_t **entry"
.Sh DESCRIPTION
The
.Fn ck_ht_next
function will increment the iterator object pointed to by
.Fa iterator
to point to the next non-empty hash table entry. If
.Fn ck_ht_next
returns
.Dv true
then the pointer pointed to by
.Fa entry
is initialized to the current hash table entry pointed to by
the
.Fa iterator
object.
.Pp
It is expected that
.Fa iterator
has been initialized using the
.Xr ck_ht_iterator_init 3
function or statically initialized using
.Dv CK_HT_ITERATOR_INITIALIZER.
.Sh RETURN VALUES
If
.Fn ck_ht_next
returns
.Dv true
then the object pointed to by
.Fa entry
points to a valid hash table entry. If
.Fn ck_ht_next
returns
.Dv false
then value of the object pointed to by
.Fa entry
is undefined.
.Sh ERRORS
Behavior is undefined if
.Fa iterator
or
.Fa ht
are uninitialized.
