问题
I am wondering which Win32 API call is creating the files with UNICODE path. Just to make sure, I am not talking about the content here only the file path. I would appreciate if somebody would hit me with an MSDN url, my google fu failed this time.
Thanks a million in advance.

See CreateFile msdn link: http://msdn.microsoft.com/en-us/library/windows/desktop/aa363858%28v=vs.85%29.aspx, if you pass a unicode string to the lpFileName parameter then the unicode version of CreateFile will be used.
Also you need to open the file in binary mode see this discussion on msdn forum: http://social.msdn.microsoft.com/forums/en-US/vclanguage/thread/71fa98ca-e757-4099-8f7f-fefcfe645298 which points to this msdn article: http://msdn.microsoft.com/en-us/library/c4cy2b8e%28vs.71%29.aspx

The principal tag on this question is "c++" not "windows. Now, unless that was just a all-too-common cheat to get a windows api question in front of a larger - mostly unrelated - audience, the answer should be slightly relevant to c++.
As such, in a C++ app, there are a number of std:: specializations that can take wchar_t. wofstream for example.
