.SH NAME
dictNext  - search for next value in dictionary.
.SH SYNOPSIS
.Ss
#include <util/dict.h>
.Se
.Ss
void *dictNext(dictCtx dict, char **id, void **plock);

.Se

.SH ARGUMENTS
dict - dictionary to iterate over.
.br
id - pointer to identifier of last item found, or
.br
pointer to NULL to retrieve first.
.br
plock - place for value lock (or NULL).

.SH DESCRIPTION
Can be used to iterate through values in the dictionary.
The order is the order of the hash of the ids, which
isn't usefully externally.  Will return the value if 
found, or NULL if not.  If <plock> is non-NULL, then
the lock returned in <plock> will be associated with
the returned value.  Until this lock is passed to
dictReleaseLock(), the value will not be passed to the
dictCleanupFunc callback (see dictCleanup()).

MT-Level: Safe if <dict> thread-safe.

.SH "RETURN VALUE"
plock - set to value lock.
.br
id - pointer to id of found value
