 *
 * Purpose     :  Contains wrappers for system-specific sockets code,
 *                so that the rest of Junkbuster can be more
 *                OS-independent.  Contains #ifdefs to make this work
 *                on many platforms.

 *
 * Revisions   :
 *    $Log: jbsockets.h,v $
 *    Revision 1.14  2008/12/20 14:53:55  fabiankeil
 *    Add config option socket-timeout to control the time
 *    Privoxy waits for data to arrive on a socket. Useful
 *    in case of stale ssh tunnels or when fuzz-testing.
 *
 *    Revision 1.13  2008/03/21 11:13:59  fabiankeil
 *    Only gather host information if it's actually needed.
 *    Also move the code out of accept_connection() so it's less likely
 *    to delay other incoming connections if the host is misconfigured.
 *
 *    Revision 1.12  2006/07/18 14:48:46  david__schmidt
 *    Reorganizing the repository: swapping out what was HEAD (the old 3.1 branch)
 *    with what was really the latest development (the v_3_0_branch branch)
 *
 *    Revision 1.9.2.1  2002/05/26 23:41:27  joergs
 *    AmigaOS: Fixed wrong type of len in write_socket()
 *
 *    Revision 1.9  2002/04/08 20:31:41  swa
 *    fixed JB spelling
 *
 *    Revision 1.8  2002/03/26 22:29:54  swa
 *    we have a new homepage!
 *
 *    Revision 1.7  2002/03/24 13:25:43  swa
 *    name change related issues
 *
 *    Revision 1.6  2002/03/13 00:27:05  jongfoster
 *    Killing warnings
 *
 *    Revision 1.5  2002/03/09 20:03:52  jongfoster
 *    - Making various functions return int rather than size_t.
 *      (Undoing a recent change).  Since size_t is unsigned on
 *      Windows, functions like read_socket that return -1 on
 *      error cannot return a size_t.
 *
 *      THIS WAS A MAJOR BUG - it caused frequent, unpredictable
 *      crashes, and also frequently caused JB to jump to 100%
 *      CPU and stay there.  (Because it thought it had just
 *      read ((unsigned)-1) == 4Gb of data...)
 *
 *    - The signature of write_socket has changed, it now simply
 *      returns success=0/failure=nonzero.
 *
 *    - Trying to get rid of a few warnings --with-debug on
 *      Windows, I've introduced a new type "jb_socket".  This is
 *      used for the socket file descriptors.  On Windows, this
 *      is SOCKET (a typedef for unsigned).  Everywhere else, it's
 *      an int.  The error value can't be -1 any more, so it's
 *      now JB_INVALID_SOCKET (which is -1 on UNIX, and in
 *      Windows it maps to the #define INVALID_SOCKET.)
 *
 *    - The signature of bind_port has changed.
 *
 *    Revision 1.4  2002/03/07 03:51:36  oes
 *     - Improved handling of failed DNS lookups
 *     - Fixed compiler warnings etc
 *
 *    Revision 1.3  2001/07/29 19:01:11  jongfoster
 *    Changed _FILENAME_H to FILENAME_H_INCLUDED.
 *    Added forward declarations for needed structures.
 *
 *    Revision 1.2  2001/06/07 23:06:09  jongfoster
 *    The host parameter to connect_to() is now const.
 *
 *    Revision 1.1.1.1  2001/05/15 13:58:54  oes
 *    Initial import of version 2.9.3 source tree
 *
