type C_AnimationTargetFunc = CDouble -> Ptr () -> IO ()

Type for the callback on the (unwrapped) C side.

drop_closures_AnimationTargetFunc :: AnimationTargetFunc -> AnimationTargetFunc_WithClosures

A simple wrapper that ignores the closure arguments.

dynamic_AnimationTargetFunc

Arguments

:: (HasCallStack, MonadIO m)

=> FunPtr C_AnimationTargetFunc

-> Double

value: The animation value

-> Ptr ()

userData: The user data provided when creating the target

-> m ()

Given a pointer to a foreign C function, wrap it into a function callable from Haskell.

genClosure_AnimationTargetFunc :: MonadIO m => AnimationTargetFunc -> m (GClosure C_AnimationTargetFunc)

Wrap the callback into a GClosure.

mk_AnimationTargetFunc :: C_AnimationTargetFunc -> IO (FunPtr C_AnimationTargetFunc)

Generate a function pointer callable from C code, from a C_AnimationTargetFunc.

noAnimationTargetFunc :: Maybe AnimationTargetFunc

A convenience synonym for Nothing :: Maybe AnimationTargetFunc.

noAnimationTargetFunc_WithClosures :: Maybe AnimationTargetFunc_WithClosures

A convenience synonym for Nothing :: Maybe AnimationTargetFunc_WithClosures.

wrap_AnimationTargetFunc :: Maybe (Ptr (FunPtr C_AnimationTargetFunc)) -> AnimationTargetFunc_WithClosures -> C_AnimationTargetFunc

Wrap a AnimationTargetFunc into a C_AnimationTargetFunc.
