int_hash

Converts a pointer to a int to a hash value.

It can be passed to g_hash_table_new as the hash_func parameter, when using non-null pointers to integer values as keys in a GenericSet.

Note that this function acts on pointers to int, not on int directly: if your hash table's keys are of the form `GINT_TO_POINTER (n)`, use direct_hash instead.

Parameters:

Returns:
