- * Revision 1.12 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 1.10 2002/03/07 03:50:19 oes
- * - Improved handling of failed DNS lookups
- * - Fixed compiler warnings
- *
- * Revision 1.9 2001/10/25 03:40:48 david__schmidt
- * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
- * threads to call select() simultaneously. So, it's time to do a real, live,
- * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__
- * (native). Both versions will work, but using __OS2__ offers multi-threading.
