[Help-gnutls] Application Data Spanning Mulitple TLS Records

[Rich Fought]

I'm sending large messages greater than 16k over TLS, so I'm having to 
deal with multiple records.

Is there any way in GnuTLS to determine how many records constitute a 
complete message
(perhaps an indicator in the record header, for instance), or is this 
left to the application layer?

How is this situation generally handled?

Thanks,
Rich
