Compiler: gcc 1.35
Machine:  VAX 11/750
OS:       Unix 4.3 BSD
Problem:  ioctl function call returns error
Program:  test.c

#include <sys/ioctl.h>

struct sgttyb arg;

void main()
{
  if (ioctl(0, TIOCGETP, &arg) < 0)
    perror("ioctl");
}

Compiled with:
  gcc -g -o test test.c

Output:
  ioctl: Inappropriate ioctl for device

I don't know if this a problem with gcc or what, but when I compile the
same program using cc, there is no output (as expected).  Any help would
be useful.  Please respond via e-mail

TIA,
