[PATCH v2 4/4] mingw: add fallback for rmdir in case directory is in use

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Heiko Voigt <heiko.voigt@xxxxxxx>

The same logic as for unlink and rename also applies to rmdir. For
example in case you have a shell open in a git controlled folder. This
will easily fail. So lets be nice for such cases as well.
