Subject: [9fans] portability question
Date: Wed, 16 Jun 2010 11:11:09 +0200 [thread overview]
Message-ID: <AANLkTinYjxYQEDBK5u2kohjRwdZA-wIB9hK8nVVnITuV@mail.gmail.com> (raw)
Can someone clarify why the program included outputs 'AB000000' (as I
expect) on 32 bit systems and 'FFFFFFFFAB000000' on 64 bit systems?
where all those 1's came from? what's the portable way of doing this?
sorry for newbie questions like this.
unsigned long l;
unsigned char c;
l = 0L;
c = 0xAB;
l |= c << 24;
printf("%lX\n", l);
