NAME

       FBB::LocalClientSocket - Client Socket connecting to a Server in the Unix Domain

SYNOPSIS

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

DESCRIPTION

       An  FBB::LocalClientSocket  may  be constructed to connect to a server process in the Unix
       Domain. The socket made available by the FBB:LocalClientSocket 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::LocalClientSocket connects, The std::ostream is  used  to
       send  information  to  the  server  process  to which the FBB::LocalClientSocket 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.

NAMESPACE

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

INHERITS FROM

       FBB::LocalSocketBase

CONSTRUCTOR

       o      LocalClientSocket():
              This constructor merely creates a FBB::LocalClientSocket object. Before it  can  be
              used, its open() member must be called.

       o      LocalClientSocket(std::string const &name):
              This constructor initializes an FBB::LocalClientSocket object, using the named Unix
              Domain socket to connect to the server using  the  named  Unix  Domain  socket.  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.
              The copy constructor is not available.

MEMBER FUNCTION

       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.

       o      open(std::string const &name):
              This  member  function  prepares  the  FBB::LocalClientSocket  object,  constructed
              earlier  using  the  default constructor, for use.  The named Unix Domain socket is
              used to connect to the server using the named Unix Domain socket. 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() should be used.
