Subject: In the Win32 implementation, strip trailing slash(es) for non-root
X-Git-Tag: GLIB_2_9_1~56
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4a964f25668a26caae35122eb824e35175d0de1c;p=platform%2Fupstream%2Fglib.git

In the Win32 implementation, strip trailing slash(es) for non-root

2005-12-01  Tor Lillqvist  <tml@novell.com>

	* glib/gstdio.c (g_stat): In the Win32 implementation, strip
	trailing slash(es) for non-root folders. stat() fails if non-root
	folders are specified with trailing slashes. It's too much hassle
	to demand that callers strip such slashes themselves, especially
	as it is easy to get it wrong and strip the slash of a root
	folder.
	(g_rename): On NT-based Windows, use MoveFileEx() with
	MOVEFILE_REPLACE_EXISTING to better match Unix behaviour.
