   Whoop!  Whoop!  Confusion alert!

   Does this mean `the argument p should be a null-pointer-to-char', or
   does it mean `the argument p should be a pointer-to-char holding the
   address of an int whose value is zero', or does it mean something else?

   It is impossible for p to have the `value ... zero' because p is a
   pointer---Pointers Are Not Integers---but this means we must guess at
   what was really meant.

0, cast to any pointer type, is a valid pointer, by definition.
