Fixed bug 3546 - SDL_EVDEV_is_console() uses type of wrong size when …
…calling ioctl Rob When calling ioctl(fd, KDGKBTYPE, &type) in SDL_EVDEV_is_console(), we declare type as an 'int'. This should be a 'char'. The subsequent syscall, and kernel code, only writes the lower byte of the word. See: http://lxr.free-electrons.com/source/drivers/tty/vt/vt_ioctl.c?v=4.4#L399 ucval = KB_101; ret = put_user(ucval, (char __user *)arg); I've observed intermittent behavior related to this, and I can force an error condition by using an int initialized to 0xFFFFFFFF. The resulting ioctl will set type to 0XFFFFFF02, and the conditional return in SDL_EVDEV_is_console() will fail. Recommend changing to char, or masking off unused bits.
