It -is built upon the L<IO::Handle> interface and inherits all the methods defined -by L<IO::Handle>. - -C<IO::Socket> only defines methods for those operations which are common to all -types of socket. Operations which are specified to a socket in a particular -domain have methods defined in sub classes of C<IO::Socket> - -C<IO::Socket> will export all functions (and constants) defined by L<Socket>. - -=head1 CONSTRUCTOR - -=over 4 - -=item new ( [ARGS] ) - -Creates an C<IO::Socket>, which is a reference to a -newly created symbol (see the C<Symbol> package). C<new> -optionally takes arguments, these arguments are in key-value pairs. -C<new> only looks for one key C<Domain> which tells new which domain -the socket will be in. All other arguments will be passed to the -configuration method of the package for that domain, See below. - - NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE - -As of VERSION 1.18 all IO::Socket objects have autoflush turned on -by default. This was not the case with earlier releases. - - NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE - -=back - -=head1 METHODS - -See L<perlfunc> for complete descriptions of each of the following -supported C<IO::Socket> methods, which are just front ends for the -corresponding built-in functions: - - socket - socketpair - bind - listen - accept - send - recv - peername (getpeername) - sockname (getsockname) - shutdown - -Some methods take slightly different arguments to those defined in L<perlfunc> -in attempt to make the interface more flexible. These are - -=over 4 - -=item accept([PKG]) - -perform the system call C<accept> on the socket and return a new object. The -new object will be created in the same class as the listen socket, unless -C<PKG> is specified. This object can be used to communicate with the client -that was trying to connect. In a scalar context the new socket is returned, -or undef upon failure. In a list context a two-element array is returned -containing the new socket and the peer address; the list will -be empty upon failure. - -=item socketpair(DOMAIN, TYPE, PROTOCOL) - -Call C<socketpair> and return a list of two sockets created, or an -empty list on failure. - -=back - -Additional methods that are provided are: - -=over 4 - -=item timeout([VAL]) - -Set or get the timeout value associated with this socket. If called without -any arguments then the current setting is returned. If called with an argument -the current setting is changed and the previous value returned. - -=item sockopt(OPT [, VAL]) - -Unified method to both set and get options in the SOL_SOCKET level. If called -with one argument then getsockopt is called, otherwise setsockopt is called. - -=item sockdomain - -Returns the numerical number for the socket domain type. For example, for -a AF_INET socket the value of &AF_INET will be returned. - -=item socktype - -Returns the numerical number for the socket type. For example, for -a SOCK_STREAM socket the value of &SOCK_STREAM will be returned. - -=item protocol - -Returns the numerical number for the protocol being used on the socket, if -known. If the protocol is unknown, as with an AF_UNIX socket, zero -is returned. - -=item connected - -If the socket is in a connected state the the peer address is returned. -If the socket is not in a connected state then undef will be returned. - -=back - -=head1 SEE ALSO - -L<Socket>, L<IO::Handle>, L<IO::Socket::INET>, L<IO::Socket::UNIX> - -=head1 AUTHOR - -Graham Barr.
