This IOCTL command issues a SCSI Send Diagnostic command to reset the tape drive. There are no arguments for this IOCTL command.

An example of the STIOC_RESET_DRIVE command is
/* reset the tape drive */
   if (ioctl(tapefd,STIOC_RESET_DRIVE,NULL)<0)
    {
    printf("IOCTL failure. errno=%d",errno);

    exit(errno);
    }
