Detailed Description

Hash table API.

Typedef Documentation

◆ hash_free_func

typedef void(* hash_free_func) (const xmpp_ctx_t *const ctx, void *p)

Function Documentation

◆ hash_new()

hash_t* hash_new	(	xmpp_ctx_t *const	ctx,
		const int	size,
		hash_free_func	free_func
	)

allocate and initialize a new hash table

◆ hash_clone()

hash_t* hash_clone ( hash_t *const table )

allocate a new reference to an existing hash table

◆ hash_release()

void hash_release ( hash_t *const table )

release a hash table when no longer needed

◆ hash_add()

int hash_add	(	hash_t *	table,
		const char *const	key,
		void *	data
	)

add a key, value pair to a hash table.

each key can appear only once; the value of any identical key will be replaced

◆ hash_get()

void* hash_get	(	hash_t *	table,
		const char *	key
	)

look up a key in a hash table

◆ hash_drop()

int hash_drop	(	hash_t *	table,
		const char *	key
	)

delete a key from a hash table

◆ hash_num_keys()

int hash_num_keys ( hash_t * table )

return the number of keys in a hash

◆ hash_iter_new()

hash_iterator_t* hash_iter_new ( hash_t * table )

allocate and initialize a new iterator

◆ hash_iter_release()

void hash_iter_release ( hash_iterator_t * iter )

release an iterator that is no longer needed

◆ hash_iter_next()

const char* hash_iter_next ( hash_iterator_t * iter )

return the next hash table key from the iterator.

the returned key should not be freed
