20 ** Cpacket.h
21 **
22 ** Defines prototypes for all public functions in Cpacket.C.
23 **
24 ** These routines provide access to information in the header, allow
25 ** modification of data in the header and provide various logical
26 ** tests of packet integrity, etc. The version independent
27 ** routines contained here are inlined. Version independent
28 ** routines which are not inlined are defined in Cpacket.C.
29 **
30 ** In addition to the packet header, there is a small data
31 ** descriptor of one or two dwords which immediately follows the
32 ** packet header at the head of the data block. The data descriptor
33 ** contains information specific to the data block and has a format which
34 ** varies depending on the type of data structure used in the data
35 ** block. The descriptor is defined in dataBlock.h and is placed
36 ** after the packet in packetRoutines.C.
