Function dart_sys::Dart_GetNativeFieldsOfArgument

pub unsafe extern "C" fn Dart_GetNativeFieldsOfArgument(
    args: Dart_NativeArguments, 
    arg_index: c_int, 
    num_fields: c_int, 
    field_values: *mut isize
) -> Dart_Handle

Gets all the native fields of the native argument at some index. \param args Native arguments structure. \param arg_index Index of the desired argument in the structure above. \param num_fields size of the intptr_t array 'field_values' passed in. \param field_values intptr_t array in which native field values are returned. \return Success if the native fields where copied in successfully. Otherwise returns an error handle. On success the native field values are copied into the 'field_values' array, if the argument at 'arg_index' is a null object then 0 is copied as the native field values into the 'field_values' array.
