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


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


       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   available   FBB::IFdStream,   FBB::IFdStreamBuf,
       FBB::OFdStream,  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 tailor-made protocol. The latter situation implies that the sequence of input-
       and output operations is defined by the programmer.

       A Unix Domain client socket can be defined using FBB::LocalClientSocket.


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




       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::Exception 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.

       Copy and move constructors (and assignment operators) are not available.


       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::Exception exception is thrown  if  the  connection  could  not  be
              established or if the SocketBase base class could not properly be constructed.
