Compares the two gint values being pointed to and returns
TRUE if they are equal.
It can be passed to HashTable.new as the key_equal_func
parameter, when using non-NULL pointers to integers as keys in a
Note that this function acts on pointers to gint, not on gint
directly: if your hash table's keys are of the form
GINT_TO_POINTER (n), use g_direct_equal() instead.
