Paul Bakker335db3f2011-04-25 15:28:35 +00001213 * Functions requiring File System functions can now be disabled
1214 by undefining POLARSSL_FS_IO

1222 * Major argument / variable rewrite. Introduced use of size_t
1223 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +01001224 better unsigned / signed use. Renamed internal bigint types
1225 t_int and t_dbl to t_uint and t_udbl in the process

1229 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +01001230 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +00001231 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
1232 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +01001233 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
1234 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
1235 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
1236 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +00001237 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
