Subject:	tcgetattr(0, &T) fails on redirection
To:	cygwin AT sourceware DOT cygnus DOT com
MIME-Version:	1.0

The following code:

#include <sys/termios.h>

main()
{
  struct termios T;
  if (tcgetattr(0, &T) == 0)
    printf("Succeeded\n");
  else
    printf("Failed\n");
}

works when I simply execute

./program

but fails when I run

./program < file

Is the standard input file descriptor not 0 in this case ?
If so, how do I find out what it is ?
Or perhaps one can't run tcgetattr on this file descriptor ?
If its impossible, how does one put standard input into
raw mode in this case ?
