FBB::LocalClientSocket(3bobcat) 			     Unix Domain client Socket				   FBB::LocalClientSocket(3bobcat)

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:Local-
       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::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  avaiable  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::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 FUNCTION

       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.

       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::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() should be used.

EXAMPLE

       See also the localserversocket(3bobcat) example.

	   #include <iostream>
	   #include <bobcat/localclientsocket>
	   #include <bobcat/ifdstream>
	   #include <bobcat/ofdstream>

	   using namespace std;
	   using namespace FBB;

	   int main(int argc, char **argv)
	   try
	   {
	       if (argc == 1)
	       {
		   cerr << "Provide filename representing the unix domain socket
";
		   return 1;
	       }

	       LocalClientSocket client(argv[1]);
	       int fd = client.connect();
	       string line;

	       cout << "Connecting to socket " << fd << endl;

	       IFdStream in(fd);		 // stream to read from
	       OFdStream out(fd);		 // stream to write to

	       while (true)
	       {
					   // Ask for a textline, stop if empty / none
		   cout << "? ";
		   if (!getline(cin, line) || line.length() == 0)
		       return 0;
		   cout << "Line read: " << line << endl;
					   // Return the line to the server
		   out << line.c_str() << endl;
		   cout << "wrote line
";

					   // Wait for a reply from the server
		   getline(in, line);
		   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;
	   }
