Hello,
 
After so much discussion I with you guys i could at last make FTPS using lib-curl,but now i have landed into another problem.
 
The whole control connection is established between my FTPS Server(Glub Tech Secure FTP Wrapper) and the lib-curl client.All the certificate validation is done as well and the user has logged into my FTP Server over which the wrapper runs.But the problem is it creates the file in FTP Directory(Server side) and however after that it simply Stay's calm for sometime( A minute or two) and gives an error "Operation Timed Out".I am sending you the attachment of the file and I have downloaded the DLL from
http://curl.haxx.se/download/curl-7.12.2-win32-ssl-devel-mingw32.zip which is just the dll not the library.
 
My Wrapper logs show these messages(Dont know what to be trimmed off so i was giving the entire transmission summary).
