Constructor & Destructor Documentation

◆ CServerTCPSocket()

CServerTCPSocket::CServerTCPSocket	(	unsigned short	listenPort,
		const std::string &	IPaddress = `std::string("127.0.0.1")`,
		int	maxConnectionsWaiting = `50`,
		mrpt::system::VerbosityLevel	verbosityLevel = `mrpt::system::LVL_INFO`
	)

Constructor that creates the socket, performs binding, and start listening mode.

Parameters

listenPort	The port to bound to.
IPaddress	The interface to bound the socket to. By default is 127.0.0.1 for localhost, for all network interfaces use 0.0.0.0.
maxConnectionsWaiting	Maximum number of incoming connections waiting for "accept" before new ones are rejected. You can check if the socket has been created OK with "isListening".

See also: isListening

Exceptions

std::exception If there is any error creating the socket, with a textual description of the error.

◆ accept()

std::unique_ptr< CClientTCPSocket > CServerTCPSocket::accept ( int timeout_ms = -1 )

Waits for an incoming connection (indefinitely, or with a given timeout) The returned object represents the new connection, and MUST BE deleted by the user when no longer needed.

Parameters

timeout_ms The timeout for the waiting, in milliseconds. Set this to "-1" to disable timeout (i.e. timeout=infinite)

Returns: The incoming connection, or nullptr on timeout or error.
