Hmmm... there appears to be code for pfFindGeode routine in
every release of Performer so far. The pfFind<blah> routines
retur the first node of the specified type (not subclass
types) with the specified name.

If you want a more general search, examine the code in
1.0/1.1: sample/pguide/trav.c or 1.2: libpfutil/trav.c.
trav.c provides a general traversal that can be adapted to
any purpose.

The routine in the mail message has two problems.

1) It only returns the first geode it encounters.

        2) It ANDs a PFTYPE_ token. To test for
        is-a-subclass, you want to AND with PFCLASS_ tokens.
        PFTYPE_ tokens should only be used to test for
        equality.

rgds,
