27 *! 24-Mar-2003 vp Merged updates required for CCS2.2 transition.
28 *! 24-Feb-2003 kc Rearranged order of node types to temporarily support legacy message
30 *! 23-Nov-2002 gp Converted tabs -> spaces, to fix formatting.
31 *! 13-Feb-2002 jeh Added sysstacksize element to RMS_MoreTaskArgs.
32 *! 11-Dec-2000 sg Added 'misc' element to RMS_MoreTaskArgs.
33 *! 04-Dec-2000 ag Added RMS_BUFDESC command code.
34 *! C/R code value changed to allow ORing of system/user codes.
35 *! 10-Oct-2000 sg Added 'align' field to RMS_StrmDef.
36 *! 09-Oct-2000 sg Moved pre-defined message codes here from rmsdefs.h.
37 *! 02-Oct-2000 sg Changed ticks to msec.
38 *! 24-Aug-2000 sg Moved definitions that will be exposed to app developers
39 *! to a separate file, rmsdefs.h.
40 *! 10-Aug-2000 sg Added RMS_COMMANDBUFSIZE and RMS_RESPONSEBUFSIZE; added
41 *! pre-defined command/response codes; more comments.
