// Created by cgo -godefs. Enum fields in structs were fixed by hand.
// command: go tool cgo -godefs ctypes.go > types.go
//
// The purpose of this file is to have Go structs with the same memory
// layout as their C counterparts. For enums we want the underlying primitive
// types to match.
//
// TODO(stephan): Add tests that allow to detect failure on platforms other
// than Linux and changes in the underlying C types.
