Detailed Description

Socket descriptor for connection-oriented communications.

This is a class to accept connection-oriented connections. This descriptor corresponds to a socket created with accept() over a StreamSocketServer.

Example of usage:

StreamSocketServer serv ("/tmp/mysocket");
StreamSocketServerDescriptor des (serv);
Buffer b (10);
des.read(b, b.getSize());

Definition at line 44 of file StreamSocketServerDescriptor.hpp.

Constructor & Destructor Documentation

StreamSocketServerDescriptor ( const StreamSocketServer &  socket )

explicit

Constructor to accept() connections on a socket.

This constructor calls accept().

Parameters

socket

StreamSocketServer on which a new connection must be accepted.

Exceptions

runtime_error

in case of error in accept()

Definition at line 33 of file StreamSocketServerDescriptor.cpp.

{
        fd_ = accept(socket.getDescriptorNumber(), NULL, 0);
        if (fd_ < 0) {
                ERROR("accept()");
                throw std::runtime_error("Accept error");
        }
}
