SYNOPSIS

#include <ght_hash_table.h>

void *ght_next_keysize(ght_hash_table_t *p_ht, ght_iterator_t *p_it, void **pp_key, unsigned int *size);

DESCRIPTION

Return the next element in an iteration. p_ht is the hash table to iterate in, p_it is a pointer to the iterator to initialize, and pp_key is filled in with a pointer to the key for the current item. size is filled in with the size for this key

This function should be used for iteration, and must be called after ght_first_keysize() or .I ght_first().

The use of the ght_iterator_t allows for several concurrent iterations, where you would use one ght_iterator_t for each iteration. In threaded environments, you should still lock access to the hash table for insertion and removal.

WARNING

Calling this without first having called ght_first will give undefined results (probably a crash), since the iterator isn’t filled correctly.
