.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Some of the methods defined in \f(CW\*(C`Net::FTP\*(C'\fR return an object which will
be derived from this class. The dataconn class itself is derived from
the \f(CW\*(C`IO::Socket::INET\*(C'\fR class, so any normal \s-1IO\s0 operations can be performed.
However the following methods are defined in the dataconn class and \s-1IO\s0 should
be performed using these.
.ie n .IP """read($buffer, $size[, $timeout])""" 4
.el .IP "\f(CWread($buffer, $size[, $timeout])\fR" 4
.IX Item "read($buffer, $size[, $timeout])"
Read \f(CW$size\fR bytes of data from the server and place it into \f(CW$buffer\fR, also
performing any <\s-1CRLF\s0> translation necessary. \f(CW$timeout\fR is optional, if not
given, the timeout value from the command connection will be used.
.Sp
Returns the number of bytes read before any <\s-1CRLF\s0> translation.
.ie n .IP """write($buffer, $size[, $timeout])""" 4
.el .IP "\f(CWwrite($buffer, $size[, $timeout])\fR" 4
.IX Item "write($buffer, $size[, $timeout])"
Write \f(CW$size\fR bytes of data from \f(CW$buffer\fR to the server, also
performing any <\s-1CRLF\s0> translation necessary. \f(CW$timeout\fR is optional, if not
given, the timeout value from the command connection will be used.
.Sp
Returns the number of bytes written before any <\s-1CRLF\s0> translation.
.ie n .IP """bytes_read()""" 4
.el .IP "\f(CWbytes_read()\fR" 4
.IX Item "bytes_read()"
Returns the number of bytes read so far.
.ie n .IP """abort()""" 4
.el .IP "\f(CWabort()\fR" 4
.IX Item "abort()"
Abort the current data transfer.
.ie n .IP """close()""" 4
.el .IP "\f(CWclose()\fR" 4
.IX Item "close()"
Close the data connection and get a response from the \s-1FTP\s0 server. Returns
\&\fItrue\fR if the connection was closed successfully and the first digit of
the response from the server was a '2'.
