Detailed Description

An object which represents a connection between two applications.

On creation, type of ip addresses that the socket will use and the layer 4/transport layer protocol is specified.
From this, methods like .bind_to(EndPoint end_point) and .connect_to(EndPoint end_point) to give the socket an address and port so that it can start communicating with other applications.
For connectionless protocols like UDP, data can be sent and received without binding or connecting first.
Can be moved from but not copied. Members are the same across all implementations.

Constructor & Destructor Documentation

WindowsSocket() [1/3]

es::WindowsSocket::WindowsSocket	(	IpVersion	ip_version,
		Protocol	protocol )

Constructor for Socket.

Parameters

ip_version	The version of ip addresses that the socket will use.
protocol	The layer 4/transport layer protocol that the socket will use.

Member Function Documentation

accept_connection()

WindowsSocket es::WindowsSocket::accept_connection

(

)

Accepts incoming connections.

.listen(int backlog)must be called first.

Returns

New socket connected to the socket that was attempting to connect.

bind_to()

void es::WindowsSocket::bind_to

(

const EndPoint &

end_point

)

Binds a socket to the given end point.

Parameters

end_point

The endpoint that the socket will use. "0.0.0.0" will bind to all IPv4 interfaces, "::0"will bind to all IPv6 interfaces and "::"" will bind to all interfaces.

connect_to()

void es::WindowsSocket::connect_to

(

const EndPoint &

end_point

)

Connects a socket to the given end point.

Parameters

end_point

The endpoint that the socket will use.

listen_for_connections()

void es::WindowsSocket::listen_for_connections

(

int

backlog

)

Makes the socket start listening for incoming connections.

Must be bound with .bind(EndPoint end_point) before being called.

Parameters

backlog

The amount of connections that can be waiting to be accepted at a time. If the amount of connections exceeds the backlog, then new connections will be dropped. Connections can be accepted with .accept_connection.

operator=() [1/2]

WindowsSocket & es::WindowsSocket::operator= ( const WindowsSocket & )

operator=() [2/2]

WindowsSocket & es::WindowsSocket::operator= ( WindowsSocket && other )

noexcept

receive_data()

int64_t es::WindowsSocket::receive_data	(	char *	buffer,
		int	buffer_size )

Waits to receive data from the connected end point.

Must be connected to another end point.

Parameters

buffer	The buffer which data received will be placed into.
buffer_size	The size of the buffer provided.

Returns

The amount of data in bytes received.

receive_data_from()

int64_t es::WindowsSocket::receive_data_from	(	char *	buffer,
		int	buffer_size,
		EndPoint &	sender_end_point )

Waits to receive data from any endpoint.

Can only be used with connectionless protocols like UDP.

Parameters

buffer	The buffer which data received will be placed into.
buffer_size	The size of the buffer provided.
sender_end_point	An out parameter will give back the end point of the sender.

Returns

The amount of data in bytes received.

send_data()

int64_t es::WindowsSocket::send_data	(	const char *	buffer,
		int	buffer_size )

Sends data to the connected end point.

Must be connected to another end point.

Parameters

buffer	The buffer which data received will be placed into.
buffer_size	The size of the buffer provided.

Returns

The amount of data in bytes sent.

send_data_to()

int64_t es::WindowsSocket::send_data_to	(	const char *	buffer,
		int	buffer_size,
		const EndPoint &	end_point )

Sends data to the provided end point.

Must be connected to another end point.

Parameters

buffer	The buffer which data received will be placed into.
buffer_size	The size of the buffer provided.
end_point	The endpoint that the data will be sent to.

Returns

The amount of data in bytes sent.
