Hi Brian,
Sure, on a typical 64-bit system you'll see:
cat <<EOF > tst.c
#include "stdio.h"
int main (int argc, char ** argv)
{
printf("sizeof(long) = %d\n",sizeof(long));
printf("sizeof(unsigned long) = %d\n",sizeof(unsigned long));
printf("sizeof(long long) = %d\n",sizeof(long long));
return 0;
}
EOF
make tst
./tst
sizeof(long) = 8
sizeof(unsigned long) = 8
sizeof(long long) = 8
so beware of the variable sizeof(...)'s. AMD64, PPC64, and EM64T are
becoming quite popular. Its likely that, in less than two years, most
chips sold (inc. laptops) will be 64-bit-capable.
