NAME
FBB::LocalClientSocket - Client Socket connecting to a Server in the Unix DomainSYNOPSIS
#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 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
FBBAll constructors, members, operators and manipulators, mentioned in this man-page, are defined in the namespace FBB.
INHERITS FROM
FBB::LocalSocketBaseCONSTRUCTOR
- 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 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::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.

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