Unigine::Socket Class

Header:#include <UnigineStreams.h>
Inherits:Stream

This class provides basic functionality for network interaction using stream sockets.

Socket Class

Members


static SocketPtr create(int type)

Creates a socket and opens it on a given port. When the socket receives data, packets from all network interfaces will be received. When the socket sends data, the default IP address will be used.

Arguments

  • int type - Port, on which the socket will be opened.

static SocketPtr create(int type, int port)

Creates a socket for TCP or UDP connections and opens it on a given port. When the socket receives data, packets from all network interfaces will be received. When the socket sends data, the default IP address will be used.

Arguments

  • int type - Socket for TCP (SOCKET_STREAM variable) or UDP (SOCKET_DGRAM) connections.
  • int port - Port, on which the socket will be opened.

static SocketPtr create(int type, const char * host, int port)

Creates a socket for TCP or UDP connections and opens it on a given host and a given port. The host specifies the address, from and to which data will be sent.

Arguments

  • int type - Socket for TCP (SOCKET_STREAM variable) or UDP (SOCKET_DGRAM) connections.
  • const char * host - Host, on which the socket will be opened.
  • int port - Port, on which the socket will be opened.

Ptr<Socket> cast(const Ptr<Stream> & stream)

Arguments

  • const Ptr<Stream> & stream

int getFD()

Returns the socket file descriptor.

Return value

Socket file descriptor.

const char * getHost()

Returns the host name on which the socket is opened.

Return value

Host name.

int getPort()

Returns the port number on which the socket is opened.

Return value

Port number.

int accept(const Ptr<Socket> & socket)

Accepts a connection on the socket.

Arguments

  • const Ptr<Socket> & socket - Socket that is bound to an address and listens to connections.

Return value

Returns 1 if the connection is accepted; otherwise, 0.

int bind()

Binds the socket to an address figured out from the host used for socket initialization.

Return value

Returns 1 if the address is bound; otherwise, 0.

int block()

Sets up a blocking socket.

Return value

1 if the socket is opened; otherwise, 0.

int broadcast()

Sets up a broadcast socket. To create a broadcast socket, you need to create it with a broadcast host address first and then use this function.

Return value

Returns 1 if the socket is set up successfully ; otherwise, 0 is returned.

int close()

Closes the socket.

int connect()

Initiates a connection on the socket.

Return value

Returns 1 if the connection is initialized; otherwise, 0.

int listen(int num)

Makes the socket listen to connections.

Arguments

  • int num - Maximum number of pending connections.

Return value

Returns 1 if the socket has started listening; otherwise, 0.

int listenMulticastGroup()

Return value

int nodelay()

Enables Nagle's algorithm.

Return value

Returns 1 if the algorithm has been enabled successfully; otherwise, 0.

int nonblock()

Makes the socket a non-blocking one.

Return value

Returns 1 if the has become non-blocking; otherwise, 0.

int open(int port)

Opens the socket on a given port. When the socket receives data, packets from all network interfaces will be received. When the socket sends data, the default IP address will be used.

Arguments

  • int port - Port number, on which the socket will be opened.

Return value

Returns 1 if the socket is opened successfully; otherwise, 0.

int open(const char * host, int port)

Opens the socket on a given port. When the socket receives data, packets from all network interfaces will be received. When the socket sends data, the default IP address will be used.

Arguments

  • const char * host - Host name, on which the socket will be opened.
  • int port - Port number, on which the socket will be opened.

Return value

Returns 1 if the socket is opened successfully; otherwise, 0.

int recv(int size)

Resizes an internal receiving buffer for a socket.

Arguments

  • int size - Receive buffer size in bytes.

Return value

Returns 1 if the buffer is resized successfully; otherwise, 0.

int send(int size)

Resizes an internal sending buffer for a socket.

Arguments

  • int size - Send buffer size in bytes.

Return value

Returns 1 if the buffer is resized successfully; otherwise, 0.

int SOCKET_DGRAM

Description

Socket for UDP packets.

int SOCKET_STREAM

Description

Socket for TCP packets.
