Thanks :-) You will be the first to know.
While I dont think its significant anymore the code sketch you
give for receive still reflects file-based thinking. Heres another
sketch. Its not intended to keep things bouncing just a "view
from the other side". This is the type of code I have running
with my own "serialization" except no envelope layer (and
basic serialization ;-).
// Called by async framework
poll_or_FD_READ_handler( envelope_istream &is )
envelope_istream::iterator i, e;
// Following loop may run 0 or more times
e = is.end();
for( i = is.begin(); i != e; ++i)
// We have a completed envelope
xml_iarchive ia( i->payload );
ia >> am; // Requires complete input data
am(); // Application stuff
// Fall through here either because there are no more
// complete envelopes available on the connection *at this moment*.
// The envelope_istream may at this point be holding an incomplete
// parse, the assumption being that more data will arrive over the
// network and this routine will be called again.
Happy New Year!
