67ca08d5bc48 Completed connection context files Sebastien Decugis <sdecugis@nict.go.jp> parents: diff changeset	47 Architecture of this wrapper:
67ca08d5bc48 Completed connection context files Sebastien Decugis <sdecugis@nict.go.jp> parents: diff changeset	48 - we have several fifo queues (1 per stream pairs).
67ca08d5bc48 Completed connection context files Sebastien Decugis <sdecugis@nict.go.jp> parents: diff changeset	49 GnuTLS is configured to use custom push / pull functions:
67ca08d5bc48 Completed connection context files Sebastien Decugis <sdecugis@nict.go.jp> parents: diff changeset	50 - the pull function retrieves the data from the fifo queue corresponding to a stream #.
67ca08d5bc48 Completed connection context files Sebastien Decugis <sdecugis@nict.go.jp> parents: diff changeset	51 - the push function sends the data on a certain stream.
67ca08d5bc48 Completed connection context files Sebastien Decugis <sdecugis@nict.go.jp> parents: diff changeset	52 We also have a demux thread that reads the socket and store received data in the appropriate fifo
67ca08d5bc48 Completed connection context files Sebastien Decugis <sdecugis@nict.go.jp> parents: diff changeset	53
67ca08d5bc48 Completed connection context files Sebastien Decugis <sdecugis@nict.go.jp> parents: diff changeset	54 We have one gnutls_session per stream pair, and as many streams that read the gnutls records and save incoming data to the target queue.
67ca08d5bc48 Completed connection context files Sebastien Decugis <sdecugis@nict.go.jp> parents: diff changeset	55
67ca08d5bc48 Completed connection context files Sebastien Decugis <sdecugis@nict.go.jp> parents: diff changeset	56 This complexity is required because we cannot read a socket for a given stream only; we can only get the next message and find its stream.
