.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.
