ght_next(3) libghthash User Manual ght_next(3)NAMEght_next - return the next element in an iteration
SYNOPSIS
#include <ght_hash_table.h>
void *ght_next(ght_hash_table_t *p_ht, ght_iterator_t *p_it, void
**pp_key);
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.
This function should be used for iteration, and must be called after
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 inser‐
tion 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.
