Description

set_socket_paramset_socket_paramSetSocketParamSetSocketParamSetSocketParam sets the GenParamNameGenParamNameGenParamNameGenParamNamegenParamName according to GenParamValueGenParamValueGenParamValueGenParamValuegenParamValue for the specified socket connection. Available parameters are 'timeout'"timeout""timeout""timeout""timeout", '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 'timeout'"timeout""timeout""timeout""timeout" can be used to set a timeout for this socket. The timeout is given in seconds as a floating point number or as the string 'infinite'"infinite""infinite""infinite""infinite".

The parameters starting with 'SO_' or 'TCP_' set the corresponding socket options. 'SO_SNDBUF'"SO_SNDBUF""SO_SNDBUF""SO_SNDBUF""SO_SNDBUF" and 'SO_RCVBUF'"SO_RCVBUF""SO_RCVBUF""SO_RCVBUF""SO_RCVBUF" specify the size of the send respectively receive buffer of the operating system for this socket. Please be aware that this does not mean the size of one network packet but the size of the buffers where all packets are temporarily stored by your operating system. 'SO_BROADCAST'"SO_BROADCAST""SO_BROADCAST""SO_BROADCAST""SO_BROADCAST" can only be used together with UDP connections and enables broadcasting of network packets. 'TCP_NODELAY'"TCP_NODELAY""TCP_NODELAY""TCP_NODELAY""TCP_NODELAY" controls the Nagle algorithm, which optimizes the flow of small TCP packets and can only be used with TCP connections.
