Ok. I see. Definition for CSTring is
type CString = Ptr CChar
C) CInt, CDouble are available...but, concerning Storable class.
Given:
typedef struct _foostruct {
int a;
double b;
} fooStruct, *fooStructPtr;
How to do to marshall it to Haskell ?
type CFooStruct = ???
instance Storable CFooStruct where
sizeOf _ = ???
peekElement _ = ????
-- Next is certainly OK, provided well defined CFooStruct
type CFoosStructPtr = Ptr CFooStruct
I need it to marshall the Maple kernel handle into Haskell...
