Class Ftp_client.ftp_client

class ftp_client : ?event_system:Unixqueue.event_system -> ?onempty:unit -> unit -> unit -> object .. end
The ftp client is a user session that may even span several connections. However, only one server is connected at once.
  • Uq_engines.engine The FTP client is also an engine. The engine can be in one of four states:
    • `Working _: The client is still active. The int argument is currently meaningless.
    • `Done(): The client has been terminated.
    • `Error e: A violation of the FTP protocol happened, or another exception e occurred
    • `Aborted: The abort method was called

method add : ?onsuccess:(unit -> unit) ->
?onerror:(exn -> unit) -> ftp_method -> unit
Adds an FTP method to the queue of methods to execute. It is no problem to add the same method twice.

When the method could be executed successfully, the function onsuccess is called. (By default, this function does nothing.)

If the FTP server indicates an error, the function onerror is called instead. The exception is either FTP_method_temp_failure or FTP_method_perm_failure. The default for onerror is to raise the exception again, which has the effect of setting the engine state to `Error. This effectively stops the FTP client. (Hard errors like socket problems or protocol violations are not reported this way, but by directly setting the engine state to `Error.)
