[Haskell-cafe] advancePtr for ForeignPtr

Is still someone on haskell.org ? ---------- Forwarded message ---------- Date: Thu, 19 Feb 2009 21:40:08 +0100 (CET) From: Henning Thielemann To: ffi@haskell.org Subject: advancePtr for ForeignPtr I want to have an advancePtr on ForeignPtr in order create a subarray. Is this reasonable and possible? Do I have to use 'touchForeignPtr' as finalizer of the subarray's ForeignPtr in order to assert that the superarray lives at least as long as the subarray? Anyway I'd prefer a function in the standard modules than doing such things by myself.
