This violates strict aliasing rule. Referring to N1570 7.20.1.4/p1 (Integer types capable of holding object pointers): The following type designates a signed integer type with the property that any valid pointer to void can be converted to this type, then converted back to pointer to void, and the result will compare equal to the original pointer: intptr_t Answer (1 of 3): It is very important to specify if in C++ or in C, since they are not the same in this regard. The value of type void* pointed by pp is accessed via a l-value expression of incompatible type unsigned int or unsigned int* respectively. And further more long is guaranteed to be atleast 32-bits. You can convert the values from one type to another explicitly using the cast operator as follows . This is known as a standard conversion.Standard conversions affect fundamental data types, and allow the conversions between numerical types (short to int, int to float, double to int), to or from bool, and some pointer conversions.Converting to int from some smaller integer type, or to double
