Re: [Quickfix-developers] Faster logons

We actually do have a cross platform Event object that should do the =
trick with a little modification: =
http://cvs.sourceforge.net/viewcvs.py/quickfix/quickfix/src/C%2B%2B/Event=
.h?rev=3D1.4&view=3Dmarkup

It uses WaitForSingleObject and pthread_cond_timedwait.  It is hardcoded =
to wait for 100 milliseconds.  If we just add a wait() signature where =
we can pass in a value for the time, this class would probably be =
perfect.

I would also suggest that the use of process_sleep is a bad idea -
whenever I need to code a sleep-type function, I use a mutex and a
WaitForSingleObject with the sleep time as the timeout. That way, I can
interrupt the sleep (by triggering the mutex) if the reason for the
sleep has gone away (or so I don't have to wait 30 seconds to bring my
application down if I'm sleeping). Makes things much more responsive.
  An excellent idea with one very important drawback.  =
WaitForSingleObject with a timeout is a WIN32 concept.=20
  It is possible, but not necessarily easy, to code an equivalent =
functionality on a posix system using pthread_cond_timedwait.
  If QuickFIX were going to use this technique someone would have to =
beef up its cross-platform thread synchronization support.
