Hi, I came across this here in utils.c which is part of top: /* * How do we know that 16 will suffice? * Because the biggest number that we will * ever convert will be 2^32-1, which is 10 * digits. */ char *itoa(val) register int val; int can be 64 bits on a amd64 machine. Why is the author of this code so sure that we will never cross the 32 bit boundary? Erich
