       globus_hashtable_iterators - Iterators

        - Iterators.

SYNOPSIS

   Functions
       void * globus_hashtable_first (globus_hashtable_t *table)
           Initialize iterator to first hash table entry.
       void * globus_hashtable_next (globus_hashtable_t *table)
           Increment hash table iterator.
       void * globus_hashtable_last (globus_hashtable_t *table)
           Initialize iterator to last hash table entry.
       void * globus_hashtable_prev (globus_hashtable_t *table)
           Decrement hash table iterator.

Detailed Description

       Iterators.

       The iterator is initially NULL until one of globus_hashtable_first() or
       globus_hashtable_last() has been called. All other calls have no effect on iterator except
       for globus_hashtable_remove(). If the iterator points at the entry being removed, the
       iterator is moved to the next entry.

       Once an 'end' has been reached with globus_hashtable_next() or globus_hashtable_prev(),
       the iterator must again be reset with globus_hashtable_first() or globus_hashtable_last()
       before being used.

Function Documentation

   void* globus_hashtable_first (globus_hashtable_t * table)
       Initialize iterator to first hash table entry. Set iterator to first entry and return
       datum, NULL if empty

   void* globus_hashtable_last (globus_hashtable_t * table)
       Initialize iterator to last hash table entry. Set iterator to last entry and return datum,
       NULL if empty

   void* globus_hashtable_next (globus_hashtable_t * table)
       Increment hash table iterator. Set iterator to next entry and return datum, NULL if at end

   void* globus_hashtable_prev (globus_hashtable_t * table)
       Decrement hash table iterator. Set iterator to the previous entry and return datum, NULL
       if at end
