260 * Major argument / variable rewrite. Introduced use of size_t
261 instead of int for buffer lengths and loop variables for
Paul Bakkera755ca12011-04-24 09:11:17 +0000262 better unsigned / signed use. Renamed internal bigint types
263 t_int and t_dbl to t_uint and t_udbl in the process

265 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000266 * The error codes have been remapped and combining error codes
267 is now done with a PLUS instead of an OR as error codes
268 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +0000269 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
270 net_recv() now returns 0 on EOF instead of
271 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
272 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.

274 after the handshake.

276 POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
277 POLARSSL_ERR_NET_TRY_AGAIN
