8 * Purpose : Contains wrappers for system-specific sockets code,
9 * so that the rest of JunkBuster can be more
10 * OS-independent. Contains #ifdefs to make this work

40 * Revision 1.6 2002/03/13 00:27:05 jongfoster
43 * Revision 1.5 2002/03/09 20:03:52 jongfoster
44 * - Making various functions return int rather than size_t.
45 * (Undoing a recent change). Since size_t is unsigned on
46 * Windows, functions like read_socket that return -1 on
47 * error cannot return a size_t.
49 * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
50 * crashes, and also frequently caused JB to jump to 100%
51 * CPU and stay there. (Because it thought it had just
52 * read ((unsigned)-1) == 4Gb of data...)
54 * - The signature of write_socket has changed, it now simply
55 * returns success=0/failure=nonzero.
57 * - Trying to get rid of a few warnings --with-debug on
58 * Windows, I've introduced a new type "jb_socket". This is
59 * used for the socket file descriptors. On Windows, this
60 * is SOCKET (a typedef for unsigned). Everywhere else, it's
61 * an int. The error value can't be -1 any more, so it's
62 * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
63 * Windows it maps to the #define INVALID_SOCKET.)
65 * - The signature of bind_port has changed.
67 * Revision 1.4 2002/03/07 03:51:36 oes
68 * - Improved handling of failed DNS lookups
69 * - Fixed compiler warnings etc
71 * Revision 1.3 2001/07/29 19:01:11 jongfoster
72 * Changed _FILENAME_H to FILENAME_H_INCLUDED.
73 * Added forward declarations for needed structures.
75 * Revision 1.2 2001/06/07 23:06:09 jongfoster
76 * The host parameter to connect_to() is now const.
78 * Revision 1.1.1.1 2001/05/15 13:58:54 oes
79 * Initial import of version 2.9.3 source tree
