Hi,

I am trying to collect some performance statistics on our
databases using the Performer 2.2 pfFrameStats functions.

I define a class pointer, fsp using getFStats()

This call returns a correct value:
     
    fsp->query(PFSTATSVAL_GFX_GEOM_TRIS |
        PFFSTATS_BUF_PREV, &ntri, sizeof(float));
                    

This call (immediately after the above call):

    fsp->query(PFSTATSVAL_GFX_GEOM_TSTRIPSTRIS |
                 PFFSTATS_BUF_PREV, &tstriptri, sizeof(float));

returns the error message:

 5022 PF Warning/Usage: pfStats::query() - unknown
query token 0x9b8 - no data written.

What am I missing?
