- Abstract device driver for the UEFI Console.
-
- Manipulates abstractions for stdin, stdout, stderr.
-
- This device is a WIDE device and this driver returns WIDE
- characters. It this the responsibility of the caller to convert between
- narrow and wide characters in order to perform the desired operations.
-
- The devices status as a wide device is indicatd by _S_IWTTY being set in
- f_iflags.
