31 * Revision 1.6 2002/03/09 20:03:52 jongfoster
32 * - Making various functions return int rather than size_t.
33 * (Undoing a recent change). Since size_t is unsigned on
34 * Windows, functions like read_socket that return -1 on
35 * error cannot return a size_t.
37 * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
38 * crashes, and also frequently caused JB to jump to 100%
39 * CPU and stay there. (Because it thought it had just
40 * read ((unsigned)-1) == 4Gb of data...)
42 * - The signature of write_socket has changed, it now simply
43 * returns success=0/failure=nonzero.
45 * - Trying to get rid of a few warnings --with-debug on
46 * Windows, I've introduced a new type "jb_socket". This is
47 * used for the socket file descriptors. On Windows, this
48 * is SOCKET (a typedef for unsigned). Everywhere else, it's
49 * an int. The error value can't be -1 any more, so it's
50 * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
51 * Windows it maps to the #define INVALID_SOCKET.)
53 * - The signature of bind_port has changed.
55 * Revision 1.5 2002/03/03 09:18:03 joergs
56 * Made jumbjuster work on AmigaOS again.
58 * Revision 1.4 2001/10/07 15:35:13 oes
59 * Replaced 6 boolean members of csp with one bitmap (csp->flags)
61 * Revision 1.3 2001/09/12 22:54:51 joergs
62 * Stacksize of main thread increased.
64 * Revision 1.2 2001/05/23 00:13:58 joergs
65 * AmigaOS support fixed.
67 * Revision 1.1.1.1 2001/05/15 13:58:46 oes
68 * Initial import of version 2.9.3 source tree
