Hi Daniel,

 Libcurl version that I am using is "7.30.0" .
 Add to this could you point me how to use in c code :

 curl -o output-file http://ip-address/input-file

 Will it be able to download the file of actual size ?
 Does this script requires libcurl installed on remote location ?

 Please let me know .

Regards,
--Ankit
