10 * os_win32.c
11 *
12 * Used for both the console version and the Win32 GUI. A lot of code is for
13 * the console version only, so there is a lot of "#ifndef FEAT_GUI_MSWIN".
14 *
15 * Win32 (Windows NT and Windows 95) system-dependent routines.
16 * Portions lifted from the Win32 SDK samples, the MSDOS-dependent code,
17 * NetHack 3.1.3, GNU Emacs 19.30, and Vile 5.5.
18 *
19 * George V. Reilly <[email protected]> wrote most of this.
20 * Roger Knobbe <[email protected]> did the initial port of Vim 3.0.
