void ∗key;

table

Hash table pointer

key

Key used by the hash coding function to set an item

sethtitem() adds an item in the hash table pointed to by table, whether it existed or not, and returns an appropriate value. This is kind of a test and set operator.

If the key exists, the function return 1, if it doesn't, the item is stored and the function returns 0.
