457 * Major argument / variable rewrite. Introduced use of size_t
458 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +0100459 better unsigned / signed use. Renamed internal bigint types
460 t_int and t_dbl to t_uint and t_udbl in the process

464 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +0100465 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +0000466 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().

Paul Bakkera35aa542013-03-06 17:06:21 +0100468 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
469 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
