Description

get_socket_paramget_socket_paramGetSocketParamGetSocketParamGetSocketParam reads the GenParamValueGenParamValueGenParamValueGenParamValuegenParamValue of the GenParamNameGenParamNameGenParamNameGenParamNamegenParamName for the specified socket connection. Available parameters are 'timeout'"timeout""timeout""timeout""timeout", 'address_info'"address_info""address_info""address_info""address_info", 'SO_SNDBUF'"SO_SNDBUF""SO_SNDBUF""SO_SNDBUF""SO_SNDBUF", 'SO_RCVBUF'"SO_RCVBUF""SO_RCVBUF""SO_RCVBUF""SO_RCVBUF", 'SO_BROADCAST'"SO_BROADCAST""SO_BROADCAST""SO_BROADCAST""SO_BROADCAST", and 'TCP_NODELAY'"TCP_NODELAY""TCP_NODELAY""TCP_NODELAY""TCP_NODELAY".

The parameter 'address_info'"address_info""address_info""address_info""address_info" returns the IP address and port of the local and the remote side of the specified socket connection.

See set_socket_paramset_socket_paramSetSocketParamSetSocketParamSetSocketParam for a description of the other values.
