Function Documentation

cdc_hash_table_get()

enum cdc_stat cdc_hash_table_get	(	struct cdc_hash_table *	t,
		void *	key,
		void **	value
	)

Returns a value that is mapped to a key. If the key does not exist, then NULL will return.

Parameters

[in]	t	- cdc_hash_table
[in]	key	- key of the element to find
[out]	value	- pinter to the value that is mapped to a key.

Returns

CDC_STATUS_OK if the key is found, CDC_STATUS_NOT_FOUND otherwise.

cdc_hash_table_count()

size_t cdc_hash_table_count	(	struct cdc_hash_table *	t,
		void *	key
	)

Returns the number of elements with key that compares equal to the specified argument key, which is either 1 or 0 since this container does not allow duplicates.

Parameters

[in]	t	- cdc_hash_table
[in]	key	- key value of the elements to count

Returns

number of elements with key key, that is either 1 or 0.

cdc_hash_table_find()

void cdc_hash_table_find	(	struct cdc_hash_table *	t,
		void *	key,
		struct cdc_hash_table_iter *	it
	)

Finds an element with key equivalent to key.

Parameters

[in]	t	- cdc_hash_table
[in]	key	- key value of the element to search for
[out]	it	- pointer will be recorded iterator to an element with key equivalent to key. If no such element is found, past-the-end iterator is returned.
