731 * Major argument / variable rewrite. Introduced use of size_t
732 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +0100733 better unsigned / signed use. Renamed internal bigint types
734 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000735 * mpi_init() and mpi_free() now only accept a single MPI
736 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000737 * The error codes have been remapped and combining error codes
738 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +0100739 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +0000740 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().

Paul Bakkera35aa542013-03-06 17:06:21 +0100742 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
743 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
744 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
745 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +0000746 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
