#9700: Support C structures in Haskell FFI -------------------------------------+------------------------------------- Reporter: Yuras | Owner: Type: feature | Status: new request | Milestone: Priority: normal | Version: 7.8.3 Component: Compiler | Keywords: Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Unknown Unknown/Multiple | Blocked By: Type of failure: | Related Tickets: None/Unknown | Test Case: | Blocking: | Differential Revisions: Phab:D252 | -------------------------------------+------------------------------------- Comment (by svenpanne): Hmmm, I think the wiki page is confusing C types and Haskell types: * If one wants to bind to a C structure containing int/char/float/..., one has to use CInt/CChar/CFloat/... on the Haskell side. * If one wants to access Haskell stuff containing Int/Char/Float, one has to use HsInt/HsChar/HsFloat/... on the C side. Any kind of structure marshaling can't change anything about that, there's no portable correspondence between the types in both worlds. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9700#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
