Hi!
Casualy I found that RAR doesn't waits input when output redirected to
NUL. Eugeny Roshal answers me that he uses next trick:
int Flags=ioctl(1,0);
if ((Flags & 0x80)==0 || (Flags & 3)==0)
SkipPrompt=1;
(BTW, this code may be optimized to "skip = (ioctl (1,0) & 0x83) < 0x80;").
Very funny trick. :)
PS: Bart, what you may say: there tested both stdin (mask 0x1) and stdout
(mask 0x2) features (and for CON both in MS-DOS and FreeDOS both bits are
set), but may be enough to test only stdout bit (ioctl & 0x82)?
