30 * Major argument / variable rewrite. Introduced use of size_t
31 instead of int for buffer lengths and loop variables for
Paul Bakkera755ca12011-04-24 09:11:17 +000032 better unsigned / signed use. Renamed internal bigint types
33 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +000034 * mpi_init() and mpi_free() now only accept a single MPI
35 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +000036 * The error codes have been remapped and combining error codes
37 is now done with a PLUS instead of an OR as error codes
38 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +000039 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
40 net_recv() now returns 0 on EOF instead of
41 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns

44 after the handshake.
45 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
46 POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
47 POLARSSL_ERR_NET_TRY_AGAIN
