Detailed Description

SocketUDP wraps a socket using UDP protocol to send data fastly (but with less safety).

Definition at line 45 of file SocketUDP.hpp.

Constructor & Destructor Documentation

◆ SocketUDP()

sf::SocketUDP::SocketUDP ( )

Default constructor.

Member Function Documentation

◆ Bind()

bool sf::SocketUDP::Bind ( unsigned short Port)

Bind the socket to a specific port.

Parameters
Port: Port to bind the socket to
Returns
True if operation has been successful

◆ Close()

bool sf::SocketUDP::Close ( )

Close the socket.

Returns
True if operation has been successful

◆ GetPort()

unsigned short sf::SocketUDP::GetPort ( ) const

Get the port the socket is currently bound to.

Returns
Current port (0 means the socket is not bound)

◆ IsValid()

bool sf::SocketUDP::IsValid ( ) const

Check if the socket is in a valid state ; this function can be called any time to check if the socket is OK.

Returns
True if the socket is valid

◆ operator!=()

bool sf::SocketUDP::operator!= ( const SocketUDP & Other) const

Comparison operator !=.

Parameters
Other: Socket to compare
Returns
True if *this != Other

◆ operator<()

bool sf::SocketUDP::operator< ( const SocketUDP & Other) const

Comparison operator <.

Provided for compatibility with standard containers, as comparing two sockets doesn't make much sense...

Parameters
Other: Socket to compare
Returns
True if *this < Other

◆ operator==()

bool sf::SocketUDP::operator== ( const SocketUDP & Other) const

Comparison operator ==.

Parameters
Other: Socket to compare
Returns
True if *this == Other

◆ Receive() [1/2]

Socket::Status sf::SocketUDP::Receive ( char * Data,
std::size_t MaxSize,
std::size_t & SizeReceived,
IPAddress & Address,
unsigned short & Port )

Receive an array of bytes.

This function will block if the socket is blocking

Parameters
Data: Pointer to a byte array to fill (make sure it is big enough)
MaxSize: Maximum number of bytes to read
SizeReceived: Number of bytes received
Address: Address of the computer which sent the data
Port: Port on which the remote computer sent the data
Returns
Status code

◆ Receive() [2/2]

Socket::Status sf::SocketUDP::Receive ( Packet & PacketToReceive,
IPAddress & Address,
unsigned short & Port )

Receive a packet.

This function will block if the socket is blocking

Parameters
PacketToReceive: Packet to fill with received data
Address: Address of the computer which sent the packet
Port: Port on which the remote computer sent the data
Returns
Status code

◆ Send() [1/2]

Socket::Status sf::SocketUDP::Send ( const char * Data,
std::size_t Size,
const IPAddress & Address,
unsigned short Port )

Send an array of bytes.

Parameters
Data: Pointer to the bytes to send
Size: Number of bytes to send
Address: Address of the computer to send the packet to
Port: Port to send the data to
Returns
Status code

◆ Send() [2/2]

Socket::Status sf::SocketUDP::Send ( Packet & PacketToSend,
const IPAddress & Address,
unsigned short Port )

Send a packet of data.

Parameters
PacketToSend: Packet to send
Address: Address of the computer to send the packet to
Port: Port to send the data to
Returns
Status code

◆ SetBlocking()

void sf::SocketUDP::SetBlocking ( bool Blocking)

Change the blocking state of the socket.

The default behaviour of a socket is blocking

Parameters
Blocking: Pass true to set the socket as blocking, or false for non-blocking

◆ Unbind()

bool sf::SocketUDP::Unbind ( )

Unbind the socket from its previous port, if any.

Returns
True if operation has been successful
