|
|
|
4347 * mch_rename() works around a bug in rename (aka MoveFile) in
|
|
|
4348 * Windows 95: rename("foo.bar", "foo.bar~") will generate a
|
|
|
4349 * file whose short file name is "FOO.BAR" (its long file name will
|
|
|
4350 * be correct: "foo.bar~"). Because a file can be accessed by
|
|
|
4351 * either its SFN or its LFN, "foo.bar" has effectively been
|
|
|
4352 * renamed to "foo.bar", which is not at all what was wanted. This
|
|
|
4353 * seems to happen only when renaming files with three-character
|
|
|
4354 * extensions by appending a suffix that does not include ".".
|
|
|
4355 * Windows NT gets it right, however, with an SFN of "FOO~1.BAR".
|
|
|
4356 *
|
|
|
4357 * There is another problem, which isn't really a bug but isn't right either:
|
|
|
4358 * When renaming "abcdef~1.txt" to "abcdef~1.txt~", the short name can be
|
|
|
4359 * "abcdef~1.txt" again. This has been reported on Windows NT 4.0 with
|
|
|
4360 * service pack 6. Doesn't seem to happen on Windows 98.
|
|
|
4361 *
|
|
|
4362 * Like rename(), returns 0 upon success, non-zero upon failure.
|
|
|
4363 * Should probably set errno appropriately when errors occur.
