+
+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>
