1177 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +01001178 better unsigned / signed use. Renamed internal bigint types
1179 t_int and t_dbl to t_uint and t_udbl in the process

1183 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +01001184 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +00001185 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
