7.2.6. Asynchronous Message Sending Example

The following code demonstrates using the properties of a sender to manage asynchronous send operations, with the option to avoid synchronous blocking when the sender is at capacity:
C++
sender.setCapacity(MY_CAPACITY); 

// Later
bool resend = true;
while (resend)
{
  if (sender.getAvailable()>0)
  {
    sender.send(message,false);
    resend = false;
  }
  else
  {
    // May wish to do nothing here 
    // or send to log file
    std::cout << "Warning: Capacity \ full. Retry" << std::endl;
   }
}
// Later
if (sender.getUnsettled())
{
    session.sync();
}
Python
snd.capacity = MY_CAPACITY

# Later

resend = True
while (resend):
  if (snd.available()>0):
    snd.send(msg, sync = False)
    resend = False
  else:
    print "Warning: Capacity full" 

# Later   
    if (snd.unsettled()):
      ssn.sync()
