                      4:  *   Microsoft-specific extensions to the Windows NT IPX/SPX Windows
                      5:  *   Sockets interface.  These extensions are provided for use as
                      6:  *   necessary for compatibility with existing applications.  They are
                      7:  *   otherwise not recommended for use, as they are only guaranteed to
                      8:  *   work *   over the Microsoft IPX/SPX stack.  An application which
                      9:  *   uses these *   extensions may not work over other IPX/SPX
                     10:  *   implementations.  Include this header file after winsock.h and
                     11:  *   wsipx.h.
                     12:  *
                     13:  *   To open an IPX socket where a particular packet type is sent in 
                     14:  *   the IPX header, specify NSPROTO_IPX + n as the protocol parameter
                     15:  *   of the socket() API.  For example, to open an IPX socket that
                     16:  *   sets the packet type to 34, use the following socket() call:
                     17:  *
                     18:  *       s = socket(AF_IPX, SOCK_DGRAM, NSPROTO_IPX + 34);
                     19:  *
                     20:  *   Below are socket option that may be set or retrieved by specifying
                     21:  *   the appropriate manifest in the "optname" parameter of getsockopt()
                     22:  *   or setsockopt().  Use NSPROTO_IPX as the "level" argument for the
                     23:  *   call.
