ENTRY *hsearch(ENTRY item, ACTION action);
Is a structure containing two pointers:
Either ENTER or FIND. When ENTER is specified, the item is inserted in the table at an appropriate point; an existing item with the same key is not overwritten. When FIND is specified, the item is not inserted into the table. When an entry exists with the specified key, it is returned, otherwise NULL is returned.
Note that only one hash table can be active in a process at any given time.
