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 1.12 2006/07/18 14:48:46 david__schmidt
41 * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
42 * with what was really the latest development (the v_3_0_branch branch)
44 * Revision 1.9.2.1 2002/05/26 23:41:27 joergs
45 * AmigaOS: Fixed wrong type of len in write_socket()
47 * Revision 1.9 2002/04/08 20:31:41 swa
50 * Revision 1.8 2002/03/26 22:29:54 swa
51 * we have a new homepage!
53 * Revision 1.7 2002/03/24 13:25:43 swa
54 * name change related issues
56 * Revision 1.6 2002/03/13 00:27:05 jongfoster
59 * Revision 1.5 2002/03/09 20:03:52 jongfoster
60 * - Making various functions return int rather than size_t.
61 * (Undoing a recent change). Since size_t is unsigned on
62 * Windows, functions like read_socket that return -1 on
63 * error cannot return a size_t.
65 * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
66 * crashes, and also frequently caused JB to jump to 100%
67 * CPU and stay there. (Because it thought it had just
68 * read ((unsigned)-1) == 4Gb of data...)
70 * - The signature of write_socket has changed, it now simply
71 * returns success=0/failure=nonzero.
73 * - Trying to get rid of a few warnings --with-debug on
74 * Windows, I've introduced a new type "jb_socket". This is
75 * used for the socket file descriptors. On Windows, this
76 * is SOCKET (a typedef for unsigned). Everywhere else, it's
77 * an int. The error value can't be -1 any more, so it's
78 * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
79 * Windows it maps to the #define INVALID_SOCKET.)
81 * - The signature of bind_port has changed.
83 * Revision 1.4 2002/03/07 03:51:36 oes
84 * - Improved handling of failed DNS lookups
85 * - Fixed compiler warnings etc
87 * Revision 1.3 2001/07/29 19:01:11 jongfoster
88 * Changed _FILENAME_H to FILENAME_H_INCLUDED.
89 * Added forward declarations for needed structures.
91 * Revision 1.2 2001/06/07 23:06:09 jongfoster
92 * The host parameter to connect_to() is now const.
94 * Revision 1.1.1.1 2001/05/15 13:58:54 oes
95 * Initial import of version 2.9.3 source tree
