annotate src/os_win32.c @ 2793:ee48b3da9d53 v7.3.172
updated for version 7.3.172
Problem: MS-Windows: rename() might delete the file if the name differs but
it's actually the same file.
Solution: Use the file handle to check if it's the same file. (Yukihiro
Nakadaira)

| 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. | |
