How do you call enterTtyMode? If you leave tty to -1, libbrlapi will
automatically get the current console's HWND, yes.

Just cast it into an int :)
For 32bit compatibility reasons, Windows will not have >32bit HWNDs.

Then you can use enterTtyModeWithPath(NULL, 0, NULL); to get root
control.

NVDA does it.

That, however, I can't answer :)
