TIOCGWINSZ on SCO UNIX 3.2

[Steve Fullerton]

I have been trying to get the following code to work for SCO UNIX:

#include <errno.h>
#include <termios.h>
#include <sys/ioctl.h>
#include <sys/types.h>
#include <sys/stream.h>
#include <sys/ptem.h>

main()
{
   struct winsize xwin;

   if (ioctl(0, TIOCGWINSZ, &xwin) == 0)
      printf("Window size:  %d x %d\n",xwin.ws_row,xwin.ws_col);
   else
      printf("errno = %d\n",errno);
}

So far all I get is an errno of 22.  This code works fine on many other
systems (different include files though) such as Sun, HP, IBM RS/6000,
DG AViiON, etc.  If anyone has managed to get this call to work for
SCO UNIX, I would appreciate learning how.  BTW, I have SCO UNIX System V/386
3.2 Version 2.0.
