//!          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).
