In an unsafe context, the ==, !=, <, >, <=, and => operators (14.9) can be applied to values of all pointer types. The pointer comparison operators are: (void* x, void* y); bool operator <=(void* x, void* y); bool operator >=(void* x, void* y); ]]> Because an implicit conversion exists from any pointer type to the void* type, operands of any pointer type can be compared using these operators. The comparison operators compare the addresses given by the two operands as if they were unsigned integers.
