Based on the following example in the Boost C++ website:
www. boost.org/doc/libs/1_47_0/doc/html/boost_asio/example/echo/async_tcp_echo_server.cpp]doc/html/boost_asio/example/echo/async_tcp_echo_server.cpp
I tried to create a similar TCP server that waits to accept a client connection and once connected, listens to incoming data from the client.
In the given example:
Code:
int main(int argc, char* argv[])
{
try
{
if (argc != 2)
{
std::cerr << "Usage: async_tcp_echo_server <port>\n";
return 1;
}
boost::asio::io_service io_service;
using namespace std; // For atoi.
server s(io_service, atoi(argv[1]));
io_service.run();
}
catch (std::exception& e)
{
std::cerr << "Exception: " << e.what() << "\n";
}
return 0;
}
However, the io_service.run() seems to run infinitely. How do I signal this run() to stop? Or run at certain time interval so that I can still have other tasks running?

QMotif(3qt)QMotif(3qt)NAME
QMotif - The basis of the
SYNOPSIS
This class is part of the Qt Motif Extension.
#include <qmotif.h>
Inherits QEventLoop.
Public Members
QMotif ( const char * applicationClass, XtAppContext context = NULL, XrmOptionDescRec * options = 0, int numOptions = 0 )
~QMotif ()
XtAppContext applicationContext () const
Static Public Members
Display * x11Display ()
DESCRIPTION
This class is defined in the Qt Motif Extension, which can be found in the qt/extensions directory. It is not included in the main Qt API.
The QMotif class provides the basis of the Motif Extension.
QMotif only provides a few public functions, but it is at the heart of the integration. QMotif is responsible for initializing the Xt
toolkit and the Xt application context. It does not open a connection to the X server, that is done by QApplication.
The only member function in QMotif that depends on an X server connection is QMotif::initialize(). QMotif must be created before
QApplication.
Example usage of QMotif and QApplication:
static char *resources[] = {
...
};
int main(int argc, char **argv)
{
QMotif integrator( "AppClass" );
XtAppSetFallbackResources( integrator.applicationContext(),
resources );
QApplication app( argc, argv );
...
return app.exec();
}
MEMBER FUNCTION DOCUMENTATION QMotif::QMotif ( const char * applicationClass, XtAppContext context = NULL, XrmOptionDescRec * options = 0, int numOptions = 0 )
Creates QMotif, which allows Qt and Xt/Motif integration.
If context is 0, QMotif creates a default application context itself. The context is accessible through applicationContext().
All arguments passed to this function (applicationClass, options and numOptions) are used to call XtDisplayInitialize() after QApplication
has been constructed.
QMotif::~QMotif ()
Destroys QMotif.
XtAppContext QMotif::applicationContext () const
Returns the application context.
Display * QMotif::x11Display () [static]
Returns the X11 display connection used by the Qt Motif Extension.
