Hi,

Alex: As per your suggestions, i tried downloading file with curl
command line tool and it worked !
curl generated a source code which is shown below:-

Now, the problem is there are list of curl API's in the below source
code .. confused which to include and which not to in my piece of program !
But i tried to include an API called "curl_easy_setopt(hnd,
CURLOPT_FTP_FILEMETHOD, 0)", which downloads only 4KB from a given 56KB
file !
I even mentioned the number of bytes as third parameter to the API which
din't work!

Please suggest me as to which API's will be related for download of files??

/********* Sample code generated by the curl command line tool **********
 * Lines with [REMARK] below might need to be modified to make this code

 * Compile this with a suitable header include path. Then link with

 * If you use any *_LARGE options, make sure your compiler figure
