No, a ForeignPtr is a purely haskell object. The C function returns a Ptr. You could create a ForeignPtr from the Ptr if you want it to be automatically freed (calling somesort of FreeSong, presumably) when it gets garbage collected. -- David Roundy http://www.darcs.net _______________________________________________ Haskell-Cafe mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell-cafe
