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. | |

5111 * file whose short file name is "FOO.BAR" (its long file name will | |
5112 * be correct: "foo.bar~"). Because a file can be accessed by | |
5113 * either its SFN or its LFN, "foo.bar" has effectively been | |
5114 * renamed to "foo.bar", which is not at all what was wanted. This | |
5115 * seems to happen only when renaming files with three-character | |
5116 * extensions by appending a suffix that does not include ".". | |
5117 * Windows NT gets it right, however, with an SFN of "FOO~1.BAR". | |
5118 * | |
5119 * There is another problem, which isn't really a bug but isn't right either: | |
5120 * When renaming "abcdef~1.txt" to "abcdef~1.txt~", the short name can be | |
5121 * "abcdef~1.txt" again. This has been reported on Windows NT 4.0 with | |
5122 * service pack 6. Doesn't seem to happen on Windows 98. | |
5123 * | |
