750 * Major argument / variable rewrite. Introduced use of size_t
751 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +0100752 better unsigned / signed use. Renamed internal bigint types
753 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +0000754 * mpi_init() and mpi_free() now only accept a single MPI
755 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000756 * The error codes have been remapped and combining error codes
757 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +0100758 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +0000759 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().

762 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
763 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
764 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +0000765 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
