lib::Net::UDP(3User Contributed Perl Documentatiolib::Net::UDP(3)NAMENet::UDP - UDP sockets interface module
SYNOPSIS
use Socket; # optional
use Net::Gen; # optional
use Net::Inet; # optional
use Net::UDP;
DESCRIPTION
The Net::UDP module provides services for UDP
communications over sockets. It is layered atop the
Net::Inet and Net::Gen modules, which are part of the same
distribution.
Public Methods
The following methods are provided by the Net::UDP module
itself, rather than just being inherited from Net::Inet or
Net::Gen.
new Usage:
$obj = new Net::UDP;
$obj = new Net::UDP $host, $service;
$obj = new Net::UDP \%parameters;
$obj = new Net::UDP $host, $service, \%parameters;
Returns a newly-initialised object of the given
class. If called for a derived class, no validation
of the supplied parameters will be performed. (This
is so that the derived class can add the parameter
validation it needs to the object before allowing
the validation.) Otherwise, it will cause the
parameters to be validated by calling its init
method, which Net::UDP inherits from Net::Inet. In
particular, this means that if both a host and a
service are given, that an object will only be
returned if a connect() call was successful.
Protected Methods
none.
Known Socket Options
There are no object parameters registered by the Net::UDP
module itself.
Known Object Parameters
There are no object parameters registered by the Net::UDP
module itself.

TIESCALAR
Tieing of scalars to a UDP handle is supported by
inheritance from the TIESCALAR method of Net::Gen. That
method only succeeds if a call to a new method results in
an object for which the isconnected method returns true,
which is why it is mentioned in connection with this
module.
Example:
tie $x,Net::UDP,0,'daytime' or die;
$x = "\n"; $x = "\n";
print $y if defined($y = $x);
untie $x;
This is an expensive re-implementation of date on many
machines.
Each assignment to the tied scalar is really a call to the
put method (via the STORE method), and each read from the
tied scalar is really a call to the getline method (via
the FETCH method).
Exports
none
