C99 FDIS:

7.18.1.4 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
The following type designates an unsigned 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:
       uintptr_t
These types are optional.

In the past you could go to a library and read, borrow or copy any book
Today you'd get arrested for mere telling someone where the library is
