479 * Major argument / variable rewrite. Introduced use of size_t
480 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +0100481 better unsigned / signed use. Renamed internal bigint types
482 t_int and t_dbl to t_uint and t_udbl in the process

484 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +0000485 * The error codes have been remapped and combining error codes
486 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +0100487 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +0000488 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().

491 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
492 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
493 after the handshake.
