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
listenPortThe port to bound to.
IPaddressThe interface to bound the socket to. By default is 127.0.0.1 for localhost, for all network interfaces use 0.0.0.0.
maxConnectionsWaitingMaximum 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::exceptionIf 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_msThe 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.
