That's only correct for machines with 32-bit ints.  In any case, POSIX
only specifies that pid_t is a signed integer type... it could be any
size supported by the implementation.  For portability, you probably
want to cast to the `biggest' type and use the appropriate printf
specifier, e.g.

   printf("%ld", (long)pid_t);
or
   printf("%jd", (intmax_t)pid_t); // C99
