Member Enumeration Documentation

Error

enum fge::net::Socket::Error

inherited

The error codes.

Type

enum fge::net::Socket::Type

inherited

The possible types of sockets.

Member Function Documentation

accept()

fge::net::Socket::Error fge::net::SocketListenerTcp::accept

(

fge::net::SocketTcp &

socket

)

Accept a new connection.

Parameters

socket

The socket to accept the connection into

Returns

Error::ERR_NOERROR if successful, otherwise an error code

close()

void fge::net::Socket::close ( )

inherited

Close the socket.

create()

fge::net::Socket::Error fge::net::SocketListenerTcp::create ( )

overridevirtual

Create the socket listener.

Returns

Error::ERR_NOERROR if successful, otherwise an error code

Implements fge::net::Socket.

getAddressType()

IpAddress::Types fge::net::Socket::getAddressType ( ) const

inlinenodiscardinherited

Get the address type of the socket.

By default, the address type is Ipv4.

Returns

The address type of the socket (Ipv4 or Ipv6)

getLocalAddress()

fge::net::IpAddress fge::net::Socket::getLocalAddress ( ) const

nodiscardinherited

Get the local address of the socket.

From MSDN: This function provide the only way to determine the local association that has been set by the system.

Returns

The local address of the socket or fge::net::IpAddress::None if there was an error

getLocalPort()

fge::net::Port fge::net::Socket::getLocalPort ( ) const

nodiscardinherited

Get the local port of the socket.

From MSDN: This function provide the only way to determine the local association that has been set by the system.

Returns

The local port of the socket or 0 if there was an error

getPlatformSpecifiedError()

static int fge::net::Socket::getPlatformSpecifiedError ( )

staticnodiscardinherited

Get the last platform specific error code.

Returns

The last platform specific error code

getRemoteAddress()

fge::net::IpAddress fge::net::Socket::getRemoteAddress ( ) const

nodiscardinherited

Get the remote address of the socket.

From MSDN: For datagram sockets, only the address of a peer specified in a previous connect call will be returned. Any address specified by a previous sendto call will not be returned.

Returns

The remote address of the socket or fge::net::IpAddress::None if there was an error

getRemotePort()

fge::net::Port fge::net::Socket::getRemotePort ( ) const

nodiscardinherited

Get the remote port of the socket.

From MSDN: For datagram sockets, only the address of a peer specified in a previous connect call will be returned. Any address specified by a previous sendto call will not be returned.

Returns

The remote port of the socket or 0 if there was an error

getType()

Type fge::net::Socket::getType ( ) const

inlinenodiscardinherited

Get the type of the socket.

Type can be one of the type defined in the Socket::Type enum

Returns

The type of the socket

initSocket()

static bool fge::net::Socket::initSocket ( )

staticinherited

Init the low-level socket library.

This call WSAStartup() on Windows and nothing on other platforms

Returns

true if successful, false otherwise

isBlocking()

bool fge::net::Socket::isBlocking ( ) const

nodiscardinherited

Check if the socket is in blocking mode.

Returns

true if the socket is in blocking mode, false otherwise

isValid()

bool fge::net::Socket::isValid ( ) const

nodiscardinherited

Check if the socket is valid.

The socket is valid if it has been created and not closed

Returns

true if the socket is valid, false otherwise

listen()

fge::net::Socket::Error fge::net::SocketListenerTcp::listen	(	fge::net::Port	port,
		fge::net::IpAddress const &	address )

Start listening for new connections from a port.

Parameters

port	The port to listen on
address	The address to listen on or fge::net::IpAddress::Any

Returns

Error::ERR_NOERROR if successful, otherwise an error code

select()

Error fge::net::Socket::select ( bool read, uint32_t timeoutms )

inherited

Check the socket for readability or writability.

From MSDN: The select function allows an application to determine the status of a socket.

If timeout is 0, the function returns immediately (polling).

Parameters

read	true if the socket should be checked for readability, false otherwise
timeoutms	The timeout in milliseconds

Returns

Error::ERR_NOERROR if the socket is ready, otherwise an error code

setAddressType()

void fge::net::Socket::setAddressType ( IpAddress::Types type )

inherited

Set the address type of the socket.

When the address type is changed, the socket is closed and recreated.

Parameters

type	The address type of the socket (Ipv4 or Ipv6)

setBlocking()

Error fge::net::Socket::setBlocking ( bool mode )

inherited

Set the blocking mode of the socket.

Parameters

mode	The blocking mode to set

Returns

Error::ERR_NOERROR if successful, otherwise an error code

setBroadcastOption()

Error fge::net::Socket::setBroadcastOption ( bool mode )

inherited

Set if the socket support broadcast.

From MSDN: The SO_BROADCAST socket option enables the socket to send and receive broadcast messages.

Parameters

mode	The broadcast mode to set

Returns

Error::ERR_NOERROR if successful, otherwise an error code

setReuseAddress()

Error fge::net::Socket::setReuseAddress ( bool mode )

inherited

Set if the socket reuse the address.

From MSDN: The SO_REUSEADDR socket option allows the application to bind to an address that is already in use.

Parameters

mode	The reuse mode to set

Returns

Error::ERR_NOERROR if successful, otherwise an error code

uninitSocket()

static void fge::net::Socket::uninitSocket ( )

staticinherited

Shutdown the low-level socket library.
