FuncPtr
The type used by cogl for function pointers, note that this type is used as a generic catch-all cast for function pointers and the actual arguments and return type may be different.
dynamic_FuncPtr :: (HasCallStack, MonadIO m) => FunPtr C_FuncPtr -> m () Source #
Given a pointer to a foreign C function, wrap it into a function callable from Haskell.
genClosure_FuncPtr :: MonadIO m => FuncPtr -> m (GClosure C_FuncPtr) Source #
Wrap the callback into a GClosure.
