Nope, x86_x64 Windows.
Can you please double-check this? I could understand 64-bit long int,
but that's not a problem either. The problem occurs only if off_t is
_narrower_ than long int. I find it hard to believe that off_t would
be 32 bits on such a platform.
It isn't narrower that "long int", because "long int" *is 32 bits*. And,
as best I can tell, so is off_t.
sys/types.h has:
typedef long _off_t;
typedef long off_t;
...and wchar.h has the same.
But to make sure...
$ cat test.c
#include <sys/types.h>
#include <stdio.h>
int main() {
printf("// sizeof(long) == %i\n",sizeof(long));
printf("// sizeof(off_t) == %i\n",sizeof(off_t));
printf("// sizeof(void*) == %i\n",sizeof(void*));
return 0;
}
$ cl /nologo test.c
test.c
$ ./test
// sizeof(long) == 4
// sizeof(off_t) == 4
// sizeof(void*) == 8
To clarify, I wasn't actually claiming that off_t was *not* 64 bits,
although now that you've made me check that assumption, obviously I was
wrong...
Where is this documented online?
http://msdn.microsoft.com/? Well, somewhere there, anyway. MSDN is the
standard place for Microsoft developer documentation.
