 *   Windows Sockets include file for IPX/SPX.  This file contains all
 *   standardized IPX/SPX information.  Include this header file after
 *   winsock.h.
 *
 *   To open an IPX socket, call socket() with an address family of
 *   AF_IPX, a socket type of SOCK_DGRAM, and protocol NSPROTO_IPX.
 *   Note that the protocol value must be specified, it cannot be 0.
 *   All IPX packets are sent with the packet type field of the IPX
 *   header set to 0.
 *
 *   To open an SPX or SPXII socket, call socket() with an address
 *   family of AF_IPX, socket type of SOCK_SEQPACKET or SOCK_STREAM,
 *   and protocol of NSPROTO_SPX or NSPROTO_SPXII.  If SOCK_SEQPACKET
 *   is specified, then the end of message bit is respected, and
 *   recv() calls are not completed until a packet is received with
 *   the end of message bit set.  If SOCK_STREAM is specified, then
 *   the end of message bit is not respected, and recv() completes
 *   as soon as any data is received, regardless of the setting of the
 *   end of message bit.  Send coalescing is never performed, and sends
 *   smaller than a single packet are always sent with the end of
 *   message bit set.  Sends larger than a single packet are packetized
 *   with the end of message bit set on only the last packet of the
 *   send.
