Net::FTP::dataconn3p
Ftp client data connection class
Usage
# Perform IO operations on an FTP client data connection object:$num_bytes_read = $obj->read($buffer, $size);$num_bytes_read = $obj->read($buffer, $size, $timeout);$num_bytes_written = $obj->write($buffer, $size);$num_bytes_written = $obj->write($buffer, $size, $timeout);$num_bytes_read_so_far = $obj->bytes_read();$obj->abort();$closed_successfully = $obj->close();
Overview
Some of the methods defined in "Net::FTP" return an object which will be derived from this class. The dataconn class itself is derived from the "IO::Socket::INET" class, so any normal IO operations can be performed. However the following methods are defined in the dataconn class and IO should be performed using these.
- "read($buffer, $size[, $timeout])"
-
Read
$sizebytes of data from the server and place it into$buffer, also performing any <CRLF> translation necessary.$timeoutis optional, if not given, the timeout value from the command connection will be used.Returns the number of bytes read before any <CRLF> translation.
- "write($buffer, $size[, $timeout])"
-
Write
$sizebytes of data from$bufferto the server, also performing any <CRLF> translation necessary.$timeoutis optional, if not given, the timeout value from the command connection will be used.Returns the number of bytes written before any <CRLF> translation.
- bytes_read()
-
Returns the number of bytes read so far.
- abort()
-
Abort the current data transfer.
- close()
-
Close the data connection and get a response from the FTP server. Returns true if the connection was closed successfully and the first digit of the response from the server was a '2'.
