/***********************************************************************
* How to use pktdef.h:
*
* 1. Include wintab.h
* 2. if using just one packet format:
* a. Define PACKETDATA and PACKETMODE as or'ed combinations of WTPKT bits
* (use the PK_* identifiers).
* b. Include pktdef.h.
* c. The generated structure typedef will be called PACKET. Use PACKETDATA
* and PACKETMODE to fill in the LOGCONTEXT structure.
* 3. If using multiple packet formats, for each one:
* a. Define PACKETNAME. Its text value will be a prefix for this packet's
* parameters and names.
* b. Define <PACKETNAME>PACKETDATA and <PACKETNAME>PACKETMODE similar to
* 2.a. above.
* c. Include pktdef.h.
* d. The generated structure typedef will be called
* <PACKETNAME>PACKET. Compare with 2.c. above and example #2 below.
* 4. If using extension packet data, do the following additional steps
* for each extension:
* a. Before including pktdef.h, define <PACKETNAME>PACKET<EXTENSION>
* as either PKEXT_ABSOLUTE or PKEXT_RELATIVE.
* b. The generated structure typedef will contain a field for the
* extension data.
* c. Scan the WTI_EXTENSION categories to find the extension's
* packet mask bit.
* d. OR the packet mask bit with <PACKETNAME>PACKETDATA and use the
* result in the lcPktData field of the LOGCONTEXT structure.
* e. If <PACKETNAME>PACKET<EXTENSION> was PKEXT_RELATIVE, OR the
* packet mask bit with <PACKETNAME>PACKETMODE and use the result
* in the lcPktMode field of the LOGCONTEXT structure.
*
*
* Example #1. -- single packet format
*
* #include <wintab.h>
* #define PACKETDATA PK_X | PK_Y | PK_BUTTONS /@ x, y, buttons @/
* #define PACKETMODE PK_BUTTONS /@ buttons relative mode @/
* #include <pktdef.h>
* ...
* lc.lcPktData = PACKETDATA;
* lc.lcPktMode = PACKETMODE;
*
* Example #2. -- multiple formats
*
* #include <wintab.h>
* #define PACKETNAME MOE
* #define MOEPACKETDATA PK_X | PK_Y | PK_BUTTONS /@ x, y, buttons @/
* #define MOEPACKETMODE PK_BUTTONS /@ buttons relative mode @/
* #include <pktdef.h>
* #define PACKETNAME LARRY
* #define LARRYPACKETDATA PK_Y | PK_Z | PK_BUTTONS /@ y, z, buttons @/
* #define LARRYPACKETMODE PK_BUTTONS /@ buttons relative mode @/
* #include <pktdef.h>
* #define PACKETNAME CURLY
* #define CURLYPACKETDATA PK_X | PK_Z | PK_BUTTONS /@ x, z, buttons @/
* #define CURLYPACKETMODE PK_BUTTONS /@ buttons relative mode @/
* #include <pktdef.h>
* ...
* lcMOE.lcPktData = MOEPACKETDATA;
* lcMOE.lcPktMode = MOEPACKETMODE;
* ...
* lcLARRY.lcPktData = LARRYPACKETDATA;
* lcLARRY.lcPktMode = LARRYPACKETMODE;
* ...
* lcCURLY.lcPktData = CURLYPACKETDATA;
* lcCURLY.lcPktMode = CURLYPACKETMODE;
*
* Example #3. -- extension packet data "XFOO".
*
* #include <wintab.h>
* #define PACKETDATA PK_X | PK_Y | PK_BUTTONS /@ x, y, buttons @/
* #define PACKETMODE PK_BUTTONS /@ buttons relative mode @/
* #define PACKETXFOO PKEXT_ABSOLUTE /@ XFOO absolute mode @/
* #include <pktdef.h>
* ...
* UINT ScanExts(UINT wTag)
* {
* UINT i;
* UINT wScanTag;
*
* /@ scan for wTag's info category. @/
* for (i = 0; WTInfo(WTI_EXTENSIONS + i, EXT_TAG, &wScanTag); i++) {
* if (wTag == wScanTag) {
* /@ return category offset from WTI_EXTENSIONS. @/
* return i;
* }
* }
* /@ return error code. @/
* return 0xFFFF;
* }
* ...
* lc.lcPktData = PACKETDATA;
* lc.lcPktMode = PACKETMODE;
* #ifdef PACKETXFOO
* categoryXFOO = ScanExts(WTX_XFOO);
* WTInfo(WTI_EXTENSIONS + categoryXFOO, EXT_MASK, &maskXFOO);
* lc.lcPktData |= maskXFOO;
* #if PACKETXFOO == PKEXT_RELATIVE
* lc.lcPktMode |= maskXFOO;
* #endif
* #endif
