Socket::Class::Const
Constants to L<Socket::Class|Socket::Class>

Socket::Class::Const - Constants to L<Socket::Class|Socket::Class>


NAME

Socket::Class::Const - Constants to Socket::Class


SYNOPSIS


  use Socket::Class qw(...);


DESCRIPTION

Socket::Class::Const contains socket related constants which can be exported. For better performance constants are declared as scalar variables.


VARIABLES

Address Family types

$AF_INET
Internet v4 address family

$AF_INET6
Internet v6 address family

$AF_BLUETOOTH
Bluetooth address family

Protocol Family types

$PF_INET
Internet protocol family. Same as $AF_INET.

$PF_INET6
Internet v6 protocol family. Same as $AF_INET6.

$PF_BLUETOOTH
Bluetooth protocol family. Same as $AF_BLUETOOTH.

Socket types

$SOCK_STREAM
Connection oriented socket

$SOCK_DGRAM
Packet oriented socket

IP (v4/v6) Protocols

$IPPROTO_ICMP
The ICMP protocol

$IPPROTO_TCP
TCP protocol. Use together with $SOCK_STREAM.

$IPPROTO_UDP
UDP protocol. Use together with $SOCK_DGRAM.

Bluetooth Protocols

$BTPROTO_RFCOMM
Stream protocol. Use together with $SOCK_STREAM.

$BTPROTO_L2CAP
Datagram protocol. Use together with $SOCK_DGRAM.

Listen queue

$SOMAXCONN

Listen queue max size.

Send, Recv Flags

$MSG_OOB
Sends OOB data (stream-style socket such as SOCK_STREAM only).

$MSG_PEEK
Peeks at the incoming data. The data is copied into the buffer, but is not removed from the input queue.

$MSG_DONTROUTE
Specifies that the data should not be subject to routing.

$MSG_CTRUNC
Data completes record.

$MSG_TRUNC
Return the real length of the packet, even when it was longer then the passed buffer. Only valid for packet sockets.

$MSG_DONTWAIT
Return even if it would normally have blocked.

$MSG_WAITALL
The receive request will complete only when one of the following events occurs:

  - The buffer supplied by the caller is completely full. 

  - The connection has been closed. 

  - The request has been canceled.

Socket Option Levels

$SOL_SOCKET
Socket option level

$SOL_TCP
TCP option level

$SOL_UDP
UDP option level

Socket Options

$SO_ACCEPTCON
Socket is listening.

$SO_BROADCAST
The default is FALSE. This option allows transmission of broadcast messages on the socket. Valid only for protocols that support broadcasting (IPX, UDP/IPv4, and others).

$SO_DEBUG
Get or set debugging mode.

$SO_DONTROUTE
The default is FALSE. This option indicates that routing is disabled, and outgoing data should be sent on whatever interface the socket and bound to. Valid for message oriented protocols only.

$SO_ERROR
The default is zero (0). This option returns and resets the per socket–based error code.

$SO_KEEPALIVE
The default is FALSE. An application or the socket client can request that a TCP/IP service provider enable the use of keep-alive packets on TCP connections by turning on the SO_KEEPALIVE socket option.

$SO_LINGER
The default is 1 (ON). This option controls the action taken when unsent data is queued on a socket and a close() or free() is performed.

$SO_OOBINLINE
The default is FALSE. This option indicates OOB data should be returned in-line with regular data. Valid for connection oriented protocols which support out-of-band data.

$SO_RCVBUF
This option specifies the total per-socket buffer space reserved for receives.

$SO_RCVLOWAT
Receives low watermark.

$SO_RCVTIMEO
Receives time-out in milliseconds.

$SO_REUSEADDR
The default is FALSE. Allows the socket to be bound to an address that is already in use.

$SO_SNDBUF
This option specifies the total per-socket buffer space reserved for sends.

$SO_SNDLOWAT
Sends low watermark.

$SO_SNDTIMEO
Sends time-out in milliseconds.

$SO_TYPE
Get the type of the socket. (Readonly)

TCP Options

$TCP_NODELAY
Disables the Nagle algorithm for send coalescing.

Shutdown values

$SD_RECEIVE
Disable receiving on the socket.

$SD_SEND
Disable sending on the socket.

$SD_BOTH
Disable both sending and receiving on the socket.

Socket States

$SOS_INIT
Socket is created

$SOS_BOUND
Sock is bound

$SOS_LISTEN
Socket is listening

$SOS_CONNECTED
Socket is connected

$SOS_CLOSED
Socket is closed

$SOS_ERROR
Socket got an error on last send oder receive
