file transmission with ftp

[Picachu]

Hy,

I am programming with C, and I send files with ftp.

But the connection betwen the client and the server is very bad and I use to loose it. When this appends, the transmission restart from the beginig, but I want to restart it where I loose it. That means, if I send a file and when the connection breaks 80% from the file was sent. When the connection restart, I want to send only the 20% lost.

Does someone know how to do it.

Maybe you should know that I am sending a file from the client to the server, and the client must restart the transmission, I can't modify the server's code.

Thanks a lot.

error recovery

A procedure that allows a user to recover from certain errors
such as failure of either host system or transfer process. In
FTP, error recovery may involve restarting a file transfer at a
given checkpoint.

You've written an FTP client?
Or are you just doing the equivalent of this
system("ftp host file");

Thanks,

I will took an eye on this.

Excuse me, but it is the first time that I use ftp, so I don't know much about it. I think I am writting a client. I am usign FtpPut() to send the file, I hope this helps.

Thanks again.

It seems like a pretty high level interface to "ftp" you're using. Since this isn't standard C, you need to be more specific about which OS / Compiler / API you're using if you want more help on say how to use it.

My guess is read the manual page to see if any other functions talk about restarting a transmission.
