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
