| Hi Carlos,
From what I'm seeing in the source code, FlushMessageQueue will wait
for csPerfThread to process all of the messages it has waiting.
However, csPerfThread's perform loop is coded to do message handling,
then flush notification, then do a call to csoundPerformKsmps. So it
may be the case that you are calling table length right after the
message queue is done but before csoundPerformKsmps has gotten to the
processing of that event.
One thing you might be able to do is call FlushMessageQueue twice, so
that you wait until the next loop runs through, but FlushMessageQueue
also requires that a message be on the message stack or it will just
return. So something like:
csPerfThread->FlushMessageQueue();
csPerfThread->InputMessage("");
csPerfThread->FlushMessageQueue();
.. then do table stuff ..
I'm not positive if that will work to send a blank table message, but
worth a shot.
