/*
File tr_buf.h from HPL TraceAccess code
// These buffer types are taken from HP-UX vers 8.0.  In future versions, the 
// actual bit positions of these types may change (as did in 9.0 when B_SYNC
// became 0x00800000.  So these are what the SRT files use as the flags.
// The only trick comes in converting KI files to srt files and knowing that 
// the B_SYNC in the particular version of HP-UX that was traced needs to map
// to this value of B_SYNC.

// The HPL values match one for one with the values in HP-UX 8.0.  Those B_
// values that have a 9 after them are the changes from 8.0 to 9.0 values,
// so these need to be converted back to 8.0 values before processing ki
// traces.
