NAME

       FBB::ClientSocket - Client Socket connecting to a Server in the Internet

SYNOPSIS

       #include <bobcat/clientsocket>
       Linking option: -lbobcat

DESCRIPTION

       An  FBB::ClientSocket  may  be  constructed  to	connect  to  some  server  process  in	the  internet.	The  socket  made available by the
       FBB:ClientSocket may be used to initialize a std::istream and/or std::ostream. The std::istream is used to read information from the server
       process	to  which  the	FBB::ClientSocket  connects,  The  std::ostream  is  used  to  send information to the server process to which the
       FBB::ClientSocket connects.  Since a socket may be considered a file descriptor the avaiable FBB::IFdStream,  FBB::IFdStreamBuf,  FBB::OFd-
       Stream,	and FBB::OFdStreamBuf classes may be used profitably here. Note that having available a socket does not mean that this defines the
       communication protocol. It is (still) the responsibility of the programmer to comply with an existing  protocol	or  to	implement  a  tai-
       lor-made protocol. The latter situation implies that the sequence of input- and output operations is defined by the programmer.

NAMESPACE

       FBB
       All constructors, members, operators and manipulators, mentioned in this man-page, are defined in the namespace FBB.

INHERITS FROM

       FBB::SocketBase

CONSTRUCTOR

       o      ClientSocket(std::string const &host, uint16_t port):
	      This constructor initializes an FBB::ClientSocket object, preparing it for a connection to the specified port at the given host.	An
	      FBB::Errno is thrown if the socket could not be constructed. The construction of the socket does not  mean  that	a  connection  has
	      actually been established. In order to connect to the server, the member connect() (see below) should be used.  The copy constructor
	      is not available.

MEMBER FUNCTIONS

       All members of FBB::SocketBase (and thus of FBB::InetAddress) are available, as FBB::ClientSocket inherits from these classes.

       o      int connect():
	      This member returns a socket that can be used to communicate with the server process. An FBB::Errno exception is thrown if the  con-
	      nection could not be established or if the SocketBase base class could not properly be constructed.

		   getline(in, line);	   // Wait for a reply from the server
		   cout << "Answer: " << line << endl;
	       }
	       return 0;
	   }
	   catch (Errno const &err)
	   {
	       cerr << err.what() << "
" <<
		       "Can't connect to " << argv[1] << ", port " <<
		       argv[2] << endl;
	       return 1;
