NAME¶

Net::FTP::dataconn - FTP Client data connection class

SYNOPSIS¶

    # 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();

DESCRIPTION¶

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 $size bytes of data from the server and place it into $buffer, also performing any <CRLF> translation necessary. $timeout is 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 $size bytes of data from $buffer to the server, also performing any <CRLF> translation necessary. $timeout is 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'.

EXPORTS¶

None.

KNOWN BUGS¶

None.
