You're correct, we should be exporting that function. For the meanwhile I
suggest you write a function of your own to check the current geostate and
take a look at what the PFSTATE_LIGHTS attribute is set to (make sure
it's not null and if not then get the values for lights i=0 to
i<PF_MAX_LIGHTS .)

Thanks for pointing this little problem out; it will get fixed properly in
the next minor release.

Sorry for the inconvenience!

A+,

Alex.
