Functions
AlcHashTable *	AlcHashTableNew (size_t tableSz, int(keyCmp)(void , void ), unsigned(hashFn)(void ), AlcErrno dstErr)
	Creates a hash table data structure which is required by all the other AlcHashTable functions. More...

AlcHashItem *	AlcHashItemNew (void entry, void(freeFn)(void ), void key, AlcErrno *dstErr)
	Creates a hash item data structure for building into an AlcHashTable. More...

AlcErrno	AlcHashTableFree (AlcHashTable *hTbl)
	Free's the given hash table data structure and any hash table items. More...

AlcErrno	AlcHashTableEntryInsert (AlcHashTable hTbl, void key, void entry, void(freeFn)(void *))
	Inserts the given entry into the hash table. More...

AlcErrno	AlcHashItemUnlink (AlcHashTable hTbl, AlcHashItem rItem, int freeItem)
	Removes the item from the hash table, but does not free the item unless the freeItem flag is set. More...

AlcErrno	AlcHashItemInsert (AlcHashTable hTbl, AlcHashItem newItem)
	Inserts a new item into the hash table. First find the table list head by generating an index from the key using the hash function, then insert the entry into the sorted list. More...

AlcErrno	AlcHashItemFree (AlcHashItem *item)
	Free's the list item which has already been removed from the list. More...

size_t	AlcHashTableCount (AlcHashTable hTbl, AlcErrno dstErr)
	Returns the number of items in the list. More...

AlcHashItem *	AlcHashTableIterate (AlcHashTable hTbl, AlcDirection dir, int(iterFn)(AlcHashTable , AlcHashItem , void ), void iterData, AlcErrno *dstErr)
	Iterates the given function through all entries of the hash table, starting with either the first or last item. The iteration proceeds towards either the last or first item in the table. The iterated function must take the form. More...

AlcErrno	AlcHashTableUnlinkAll (AlcHashTable hTbl, int(testFn)(AlcHashTable , AlcHashItem , void ), void fnData, int freeItems)
	Unlinks all items which are matched by the given match function. If the match pointer function is NULL then all the items are unlinked. The test function should return non-zero to unlink the item passed to it. More...

AlcHashItem *	AlcHashItemGet (AlcHashTable hTbl, void key, AlcErrno *dstErr)
	Gets the item from the hash table with the matching key, it's not an error if a matching item isn't found. More...

int	AlcHashItemOrder (AlcHashTable hTbl, AlcHashItem item0, AlcHashItem *item1)
	Finds the order in which the given items would occur in the hash table. More...
