+//! @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 protocol 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 -
+//! use 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.
+//!
+//! @Note On this version the following two socket options are enabled:
+//! The only protocol level supported in this version
+//! is SOL_SOCKET (level).
+//! 1. SOCKOPT_RECV_TIMEOUT (optname)
+//! SOCKOPT_RECV_TIMEOUT configures recv and recvfrom timeout
+//! in milliseconds.
+//! In that case optval should be pointer to unsigned long.
+//! 2. SOCKOPT_NONBLOCK (optname). sets the socket non-blocking mode on
+//! or off.
+//! In that case optval should be SOCK_ON or SOCK_OFF (optval).
