9 * so that the rest of Junkbuster can be more
10 * OS-independent. Contains #ifdefs to make this work

40 * Revision 1.13 2008/03/21 11:13:59 fabiankeil
41 * Only gather host information if it's actually needed.
42 * Also move the code out of accept_connection() so it's less likely
43 * to delay other incoming connections if the host is misconfigured.
45 * Revision 1.12 2006/07/18 14:48:46 david__schmidt
46 * Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
47 * with what was really the latest development (the v_3_0_branch branch)
49 * Revision 1.9.2.1 2002/05/26 23:41:27 joergs
50 * AmigaOS: Fixed wrong type of len in write_socket()
52 * Revision 1.9 2002/04/08 20:31:41 swa
55 * Revision 1.8 2002/03/26 22:29:54 swa
56 * we have a new homepage!
58 * Revision 1.7 2002/03/24 13:25:43 swa
59 * name change related issues
61 * Revision 1.6 2002/03/13 00:27:05 jongfoster
64 * Revision 1.5 2002/03/09 20:03:52 jongfoster
65 * - Making various functions return int rather than size_t.
66 * (Undoing a recent change). Since size_t is unsigned on
67 * Windows, functions like read_socket that return -1 on
68 * error cannot return a size_t.
70 * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
71 * crashes, and also frequently caused JB to jump to 100%
72 * CPU and stay there. (Because it thought it had just
73 * read ((unsigned)-1) == 4Gb of data...)
75 * - The signature of write_socket has changed, it now simply
76 * returns success=0/failure=nonzero.
78 * - Trying to get rid of a few warnings --with-debug on
79 * Windows, I've introduced a new type "jb_socket". This is
80 * used for the socket file descriptors. On Windows, this
81 * is SOCKET (a typedef for unsigned). Everywhere else, it's
82 * an int. The error value can't be -1 any more, so it's
83 * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
84 * Windows it maps to the #define INVALID_SOCKET.)
86 * - The signature of bind_port has changed.
88 * Revision 1.4 2002/03/07 03:51:36 oes
89 * - Improved handling of failed DNS lookups
90 * - Fixed compiler warnings etc
92 * Revision 1.3 2001/07/29 19:01:11 jongfoster
93 * Changed _FILENAME_H to FILENAME_H_INCLUDED.
94 * Added forward declarations for needed structures.
96 * Revision 1.2 2001/06/07 23:06:09 jongfoster
97 * The host parameter to connect_to() is now const.
99 * Revision 1.1.1.1 2001/05/15 13:58:54 oes
100 * Initial import of version 2.9.3 source tree
