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_W32". | |
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 <george@reilly.org> wrote most of this. | |
20 * Roger Knobbe <rogerk@wonderware.com> did the initial port of Vim 3.0. | |
