IMHO a function which is supposed to return a String should return a
String. Or maybe trigger an exception. Of course, in C on most
processors a pointer-to-string will point to the empty string if the
value pointed to is preset to a zero integer. Are there processors where
the first (lowest-address) byte of a zero integer is other than 0x00?
Maybe some big-endian machines use a kind of skewed arithmetic where
integer plus-zero = 0x80000000 ?
Best regards,
