        \brief create an endpoint for communication

        The socket function creates a new socket of a certain socket type, identified
        by an integer number, and allocates system resources to it.
        This function is called by the application layer to obtain a socket handle.

        \param[in] domain           specifies the protocol family of the created socket.
                                    For example:
                                       AF_INET for network protocol IPv4
                                       AF_RF for starting transceiver mode. Notes:
                                       - sending and receiving any packet overriding 802.11 header
                                       - for optimized power consumption the socket will be started in TX
                                         only mode until receive command is activated
                                       AF_INET6 for IPv6


        \param[in] type              specifies the communication semantic, one of:
                                       SOCK_STREAM (reliable stream-oriented service or Stream Sockets)
                                       SOCK_DGRAM (datagram service or Datagram Sockets)
                                       SOCK_RAW (raw protocols atop the network layer)
                                       when used with AF_RF:
                                                                         SOCK_DGRAM - L2 socket
                                                                         SOCK_RAW - L1 socket - bypass WLAN CCA (Clear Channel Assessment)

        \param[in] protocol         specifies a particular transport to be used with
                                    the socket.
                                    The most common are IPPROTO_TCP, IPPROTO_SCTP, IPPROTO_UDP,
                                    IPPROTO_DCCP.
                                    The value 0 may be used to select a default
                                    protocol from the selected domain and type


        \return                     On success, socket handle that is used for consequent socket operations.
                                    A successful return code should be a positive number (int16)
                                    On error, a negative (int16) value will be returned specifying the error code.

        \brief Accept a connection on a socket

        This function is used with connection-based socket types (SOCK_STREAM).
        It extracts the first connection request on the queue of pending
        connections, creates a new connected socket, and returns a new file
        descriptor referring to that socket.
        The newly created socket is not in the listening state. The
        original socket sd is unaffected by this call.

        sl_Socket(), bound to a local address with sl_Bind(), and is
        listening for connections after a sl_Listen(). The argument \b
        \e addr is a pointer to a sockaddr structure. This structure
        is filled in with the address of the peer socket, as known to
        the communications layer. The exact format of the address
        returned addr is determined by the socket's address family.
        The \b \e addrlen argument is a value-result argument: it
        should initially contain the size of the structure pointed to
        by addr, on return it will contain the actual length (in

        \brief set socket options

        This function manipulate the options associated with a socket.
        Options may exist at multiple protocol levels; they are always
        present at the uppermost socket level.

        When manipulating socket options the level at which the option resides
        and the name of the option must be specified.  To manipulate options at
        the socket level, level is specified as SOL_SOCKET.  To manipulate
        options at any other level the protocol number of the appropriate proto-
        col controlling the option is supplied.  For example, to indicate that an
        option is to be interpreted by the TCP protocol, level should be set to
        the protocol number of TCP;

        The parameters optval and optlen are used to access optval -
        ues for setsockopt().  For getsockopt() they identify a
        buffer in which the value for the requested option(s) are to
        be returned.  For getsockopt(), optlen is a value-result
        parameter, initially containing the size of the buffer
        pointed to by option_value, and modified on return to
        indicate the actual size of the value returned.  If no option
        value is to be supplied or returned, option_value may be
        NULL.

        \brief Get socket options

        This function manipulate the options associated with a socket.
        Options may exist at multiple protocol levels; they are always
        present at the uppermost socket level.

        When manipulating socket options the level at which the option resides
        and the name of the option must be specified.  To manipulate options at
        the socket level, level is specified as SOL_SOCKET.  To manipulate
        options at any other level the protocol number of the appropriate proto-
        col controlling the option is supplied.  For example, to indicate that an
        option is to be interpreted by the TCP protocol, level should be set to
        the protocol number of TCP;

        The parameters optval and optlen are used to access optval -
        ues for setsockopt().  For getsockopt() they identify a
        buffer in which the value for the requested option(s) are to
        be returned.  For getsockopt(), optlen is a value-result
        parameter, initially containing the size of the buffer
        pointed to by option_value, and modified on return to
        indicate the actual size of the value returned.  If no option
        value is to be supplied or returned, option_value may be
        NULL.

        \param[in]  level           defines the protocol level for this option
