Hi,

I wrote an application that uploads a data stream to an ftp server. This
is working so far exept that I'm unable to properly finish the FTP
connection after the upload is done.

In a simple test where I'm sending a stream with 6 bytes my read callback
function is called 2 times by curl. First time i send a short string with
6 bytes length (where 6 is also my return value). Second (and last) time
curl calls the function I return a 0 to signal end of transmission. I
expected curl would quit ftp connection but instead FTP server is left
open. If I instead return CURL_READFUNC_ABORT after upload of data the ftp
server will be disconnected as expected. But this might be not the default
way for an successful upload. :-)

I also set CURLOPT_INFILESIZE_LARGE to (curl_off_t) 6. No difference in
behavior and problem is the same.

I've read all notes on curlopt_readfunction. From my point of view I do
not a "pre-matured" returning of 0 value.

What I'm doing wrong?

Thanks and cheers

Thomas
