{ wsipx.h Microsoft Windows Copyright (C) Microsoft Corporation, 1992-1999. 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. } // This is the structure of the SOCKADDR structure for IPX and SPX. type SOCKADDR_IPX = packed record sa_family : u_short; sa_netnum : Array [0..3] of Char; sa_nodenum : Array [0..5] of Char; sa_socket : u_short; end; TSOCKADDR_IPX = SOCKADDR_IPX; PSOCKADDR_IPX = ^SOCKADDR_IPX; LPSOCKADDR_IPX = ^SOCKADDR_IPX; // Protocol families used in the "protocol" parameter of the socket() API. const NSPROTO_IPX = 1000; NSPROTO_SPX = 1256; NSPROTO_SPXII = 1257;
