I modified slightly the Echo Server code sample from Apple with the
following results. One, I couldn't stream a large file from a
polling routine. More than likely it would cancel because of a
Sigterm 15.
It appears from reading the docs that the user cannot detect the end
of a stream and that the NSStreamEventEndEncountered only detects a
close. Two, when unarchiving a file in a client input stream delegate
method, if the stream terminated from the server because it was too
large, the client terminates on an unarchiver error because it didn't
get the whole stream. Third, the output stream methods shown in Echo
Server are polling methods, not delegate methods.
So:
1. How do I stream a large file between connections or is NSStream
the wrong tool? Can the stream size be modified?
2. What is the largest stream size?
3. Is it possible to detect a valid archive before I unarchive it, or
do I simply have to intercept the exception?
4. How does one trigger and make available a file an output stream so
that the delegate methods can be used?
Thank,
John MacMullin
