Stefan, dear all,
the message handlich API is currently not very sophisticated.
There is no way to do something like this very elegantly at
the time.
What you can do, however, is call sctp_receive() several times
with a small buffer (one that your program can handle), and
just not use this data.
This will read successive parts of the message (similar to a
partial delivery) and when you have read the last part of
the message, the next sctp_receive() call will give you
data from the next message.
Please note that it does not currently make sense to send a
"very large data message", i.e. one 2GB file, as one "SCTP message".
This could be attempted with the current implementation, but may
easily *block* after a full receiver window of data has been send,
but the full message was not assembled by the receiver
(who cannot have freed the receiver buffer space, unless a *true*
partial delivery API were implemented).
Regards,
Andreas
