dictNext(3)			  util/dict.h			   dictNext(3)

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	 dict‐
       Cleanup()).

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

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