This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for the CHICKEN 5 version of this egg, if it exists.
If it does not exist, there may be equivalent functionality provided by another egg; have a look at the egg index. Otherwise, please consider porting this egg to the current version of CHICKEN.
- Outdated egg!
A simple FTP client library.
Errors triggered by invalid or negative replies from the FTP server are signalled by raising a compund condition of the kinds exn and ftp. The error code of a ftp condition can be accessed with the code property.
This extension provides the ftp module.
- ftp:connect HOSTNAME USERNAME PASSWORD #!optional VERBOSE PORTprocedure
Connects to the server HOSTNAME using the FTP protocol and identifies this client with USERNAME with a given PASSWORD (all strings). If the optional argument VERBOSE is given and not #f, then a protocol of the communication with the server is written to the value of (current-error-port). PORT specifies the port-number and defaults to 21.
This procedure returns an object representing the FTP session.
- ftp:disconnect FTPprocedure
Closes the connection identified by the session object FTP.
- ftp:ftp? Xprocedure
Returns #t if X is an FTP session object, or #f otherwise.
- ftp:set-type! FTP TYPEprocedure

After the directory has been read, the port must be closed to allow further read/write operations in this FTP session.
