\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.

SL_EPROTOTYPE - illegal type parameter
SL_EACCES - permission denied
SL_ENSOCK - exceeded maximal number of socket
SL_ENOMEM - memory allocation error

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.

\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

\brief write data to TCP socket
This function is used to transmit a message to another socket.
Returns immediately after sending data to device.
In case of TCP failure an async event SL_SOCKET_TX_FAILED_EVENT is going to
be received.
In case of a RAW socket (transceiver mode), extra 4 bytes should be reserved at the end of the
frame data buffer for WLAN FCS
\param[in] sd socket handle

the message to be sent
\param[in] Len message size in bytes. Range: 1-1460 bytes
\param[in] flags Specifies the type of message
transmission. On this version, this parameter is not
supported for TCP.
For transceiver mode, the SL_RAW_RF_TX_PARAMS macro can be used to determine
transmission parameters (channel,rate,tx_power,preamble)
\return Return the number of bytes transmitted,
