Subject: Is there an ftp client library to communicate with sftp server?

Hi -

I want to write an application that links in a client library that
performs secure ftp. Are any available?
It needs to communicate with the sftp server daemon. I know this can
be done with non-secure ftp.
Do I need to simply write my own socket tools and follow a spec?
(Where would I find this?) Or has
someone done it and made it public with an API.

Thanks!

Al
