20.3. Determining Whether the Terminal Is a VC

To find out whether the current terminal is a VC, you can open /dev/tty and use VT_GETMODE to query the mode:

 struct vt_mode vtmode;  fd = open("/dev/tty", O_RDWR);  retval = ioctl(fd, VT_GETMODE, &vtmode);  if (retval < 0) {      /* This terminal is not a VC; take appropriate action */  }
