Handler
type C_Handler = CString -> Ptr () -> IO () Source #
Type for the callback on the (unwrapped) C side.
type Handler_WithClosures = Text -> Ptr () -> IO () Source #
No description available in the introspection data.
drop_closures_Handler :: Handler -> Handler_WithClosures Source #
A simple wrapper that ignores the closure arguments.
dynamic_Handler :: (HasCallStack, MonadIO m) => FunPtr C_Handler -> Text -> Ptr () -> m () Source #
Given a pointer to a foreign C function, wrap it into a function callable from Haskell.
genClosure_Handler :: MonadIO m => Handler -> m (GClosure C_Handler) Source #
Wrap the callback into a GClosure.
mk_Handler :: C_Handler -> IO (FunPtr C_Handler) Source #
Generate a function pointer callable from C code, from a C_Handler.
noHandler_WithClosures :: Maybe Handler_WithClosures Source #
A convenience synonym for Nothing :: Maybe Handler_WithClosures
