Function dart_sys::Dart_SetReturnValue

pub unsafe extern "C" fn Dart_SetReturnValue(
    args: Dart_NativeArguments, 
    retval: Dart_Handle
)

Sets the return value for a native function.

If retval is an Error handle, then error will be propagated once the native functions exits. See Dart_PropagateError for a discussion of how different types of errors are propagated.
