[clamav-users] 回复: 回复: Cannot get 'fd' when using API 'cl_scanfile'

[Gao Hui]

Hi Ged,
I do some little tests and I think I find the problem for now.
For example, if I want to scan 'D:\test' and pass the char into it. The code will translate it to wchar and it becames '\\?\D:\test'. It will open the same folder if you put them in folder's address bar. But _wopen will return -1 if you use '\\?\D:\test'.

I don't really do Windows, so even if you'd told us which versions of
everything you are using it wouldn't have helped me.  But I do have
some experience of fixing things.

In a case like this I'd probably look for something which uses the API
calls to the library successfully, and run that through the same debug
processes which you are using for the code which fails.  Comparing the
code which succeeds with the code which fails should shed some light.

You probably have something which succeeds in the ClamAV distribution.
