Method accept

C++/inetserverstream.cpp:177–217

* @brief Accept a connection and return a socket connected to the client. * * Waits for a client to connect and returns a pointer to a inet_stream object * which can be used to communicate with the client. * * @param numeric Specifies if the client's parameter (IP address, port) should * be delivered numerically in the src_host/src_port parameters. * @param accept_flags Flags specified in `

 * @returns A pointer to a connected TCP/IP client socket object.
