source control api help

After a week of re familiarizing myself with c and c++ I was final able to start writing a source control plug in. I am stuck at SCS_GetRootFolderLength and SCS_GetRootFolder though.   Dreamweaver calls both functions but immediately after gives the error “An error occurred – cannot open remote folder <rootName>” I have tried every combination Folder length around the folder name length. I have tried with back slashed before and after the name. No matter what I do Dreamweaver never calls SCS_GetFolderListLength
