Ok - here's a question for the stdio internal gurus...
ftell() is defined to return a 'long' (32 bits).
fpos_t is defined as a 'long long' (64 bits).
fgetpos() accepts an fpos_t as it's second argument, and is
implemented as:
{
int retval;
retval = (*pos = ftell(fp)) == (fpos_t) -1;
return (retval);
}
Now - given this - how will fgetpos() ever succeed on a file
position greater than 2**32 - since ftell() can't return anything
larger than that...
Moreover - what if you do an fsetpos() on something larger than
2**32 and then do an fgetpos() to see if it actually worked...
If this is the case... then why is fpos_t a 'long long'? If, in fact,
it can never be set that large?
I must be missing something here...
