[vlc-devel] commit: WinCE: add replacement getcwd() function (Pierre Ynard )

[git version control]

vlc | branch: master | Pierre Ynard <linkfanel at yahoo.fr> | Thu May 21 00:11:37 2009 +0200| [be531987f668b1cea7aaa103638bffc97492feea] | committer: Pierre Ynard 

WinCE: add replacement getcwd() function

As WinCE doesn't support working directories, this function is
basically empty, and merely returns an error.
