Masaki's question raises a question with me. In the errant example from
page 147 of the Programming Guide, the call to pfNodeTravMask uses the
`setMode' parameter value of PFTRAV_SET_FROM_CHILD. According to the
manuals I have (Prog. Guide and Reference Pages) the only valid values
for that parameter are PFTRAV_SELF and PFTRAV_DESCEND. I can't find any
mention of PFTRAV_SET_FROM_CHILD except in the example on page 147. Is
PFTRAV_SET_FROM_CHILD a valid value, and, if so, where can we find an
explanation of it.
