8 * Purpose : Contains functions to connect to a server, possibly
9 * using a "gateway" (i.e. HTTP proxy and/or SOCKS4
10 * proxy). Also contains the list of gateway types.

43 * - Making various functions return int rather than size_t.
44 * (Undoing a recent change). Since size_t is unsigned on
45 * Windows, functions like read_socket that return -1 on
46 * error cannot return a size_t.
48 * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
49 * crashes, and also frequently caused JB to jump to 100%
50 * CPU and stay there. (Because it thought it had just
51 * read ((unsigned)-1) == 4Gb of data...)
53 * - The signature of write_socket has changed, it now simply
54 * returns success=0/failure=nonzero.
56 * - Trying to get rid of a few warnings --with-debug on
57 * Windows, I've introduced a new type "jb_socket". This is
58 * used for the socket file descriptors. On Windows, this
59 * is SOCKET (a typedef for unsigned). Everywhere else, it's
60 * an int. The error value can't be -1 any more, so it's
61 * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
62 * Windows it maps to the #define INVALID_SOCKET.)
64 * - The signature of bind_port has changed.
66 * Revision 1.3 2001/07/29 18:58:15 jongfoster
67 * Removing nested #includes, adding forward declarations for needed
68 * structures, and changing the #define _FILENAME_H to FILENAME_H_INCLUDED.
70 * Revision 1.2 2001/06/07 23:12:14 jongfoster
71 * Removing gateways[] list - no longer used.
72 * Replacing function pointer in struct gateway with a directly
73 * called function forwarded_connect(), which can do the common
74 * task of deciding whether to connect to the web server or HTTP
76 * Replacing struct gateway with struct forward_spec
78 * Revision 1.1.1.1 2001/05/15 13:58:54 oes
