12How to use pktdef.h:
13
141. Include wintab.h
152. if using just one packet format:
16 a. Define PACKETDATA and PACKETMODE as or'ed combinations of WTPKT bits
17 (use the PK_* identifiers).
18 b. Include pktdef.h.
19 c. The generated structure typedef will be called PACKET. Use PACKETDATA
20 and PACKETMODE to fill in the LOGCONTEXT structure.
213. If using multiple packet formats, for each one:
22 a. Define PACKETNAME. Its text value will be a prefix for this packet's
23 parameters and names.
24 b. Define <PACKETNAME>PACKETDATA and <PACKETNAME>PACKETMODE similar to
25 2.a. above.
26 c. Include pktdef.h.
27 d. The generated structure typedef will be called
28 <PACKETNAME>PACKET. Compare with 2.c. above and example #2 below.
294. If using extension packet data, do the following additional steps
30 for each extension:
31 a. Before including pktdef.h, define <PACKETNAME>PACKET<EXTENSION>
32 as either PKEXT_ABSOLUTE or PKEXT_RELATIVE.
33 b. The generated structure typedef will contain a field for the
34 extension data.
35 c. Scan the WTI_EXTENSION categories to find the extension's
36 packet mask bit.
37 d. OR the packet mask bit with <PACKETNAME>PACKETDATA and use the
38 result in the lcPktData field of the LOGCONTEXT structure.
39 e. If <PACKETNAME>PACKET<EXTENSION> was PKEXT_RELATIVE, OR the
40 packet mask bit with <PACKETNAME>PACKETMODE and use the result
41 in the lcPktMode field of the LOGCONTEXT structure.
