6 Net::FTP::dataconn - FTP Client data connection class
7
9 # Perform IO operations on an FTP client data connection object:
10
11 $num_bytes_read = $obj->read($buffer, $size);
12 $num_bytes_read = $obj->read($buffer, $size, $timeout);
13
14 $num_bytes_written = $obj->write($buffer, $size);
15 $num_bytes_written = $obj->write($buffer, $size, $timeout);
16
17 $num_bytes_read_so_far = $obj->bytes_read();
18
19 $obj->abort();
20
21 $closed_successfully = $obj->close();
22
24 Some of the methods defined in "Net::FTP" return an object which will
25 be derived from this class. The dataconn class itself is derived from
26 the "IO::Socket::INET" class, so any normal IO operations can be
27 performed. However the following methods are defined in the dataconn
28 class and IO should be performed using these.
29
30 "read($buffer, $size[, $timeout])"
31 Read $size bytes of data from the server and place it into $buffer,
32 also performing any <CRLF> translation necessary. $timeout is
33 optional, if not given, the timeout value from the command
34 connection will be used.
35
36 Returns the number of bytes read before any <CRLF> translation.
37
38 "write($buffer, $size[, $timeout])"
39 Write $size bytes of data from $buffer to the server, also
40 performing any <CRLF> translation necessary. $timeout is optional,
41 if not given, the timeout value from the command connection will be
42 used.
43
44 Returns the number of bytes written before any <CRLF> translation.
45
46 "bytes_read()"
47 Returns the number of bytes read so far.
48
49 "abort()"
50 Abort the current data transfer.
51
52 "close()"
53 Close the data connection and get a response from the FTP server.
54 Returns true if the connection was closed successfully and the
55 first digit of the response from the server was a '2'.
56
58 None.
59
61 None.
