[Haskell-cafe] About pointer taken by C lib in FFI.

Hi, Say I have some data, and `poke` into a Ptr. Then I pass the Ptr to some function in C lib. The C lib stores the Ptr somewhere to use later. My question is, how does GHC handle the finalizing of the Ptr? Does it track the "used by foreign lib"? -- 竹密岂妨流水过 山高哪阻野云飞 And for G+, please use magiclouds#gmail.com.
