NAME

       dictNext  - search for next value in dictionary.

SYNOPSIS

       #include <util/dict.h>

       void *dictNext(dictCtx dict, char **id, void **plock);

ARGUMENTS

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

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.

RETURN VALUE

       plock - set to value lock.
       id - pointer to id of found value
