使用 Windows DLL 是（在我看来）直接使用 Win32 API 的最佳方式。
如果您查看 Go 安装的 src/syscall 目录，您可以找到一个名为 mksyscall_windows.go 的文件。这似乎是 Go 团队管理所有 DLL 包装器的方式。
使用go generate 生成您的代码
看看syscall_windows.go 是如何使用它的。具体来说，它有以下go generate 命令：
//go:generate go run mksyscall_windows.go -output zsyscall_windows.go syscall_windows.go security_windows.go
定义 Win32 API 类型
然后他们定义他们的类型。您需要自己手动执行此操作。
有时这是一个挑战，因为保持结构字段的大小和对齐方式至关重要。我使用Visual Studio Community Edition 来探索微软定义的大量基本类型，以确定它们的 Go 等价物。
Windows 对字符串使用 UTF16。所以你将把它们表示为*uint16。使用 syscall.UTF16PtrFromString 从 Go 字符串生成一个。
注释要导出的 Win32 API 函数
mksyscall_windows.go 的全部意义在于生成所有样板代码，因此您最终会得到一个为您调用 DLL 的 Go 函数。
这是通过添加注释来完成的（Go cmets）。
例如，在syscall_windows.go 中有这些注释：
//sys GetLastError() (lasterr error)
//...
//sys CreateHardLink(filename *uint16, existingfilename *uint16, reserved uintptr) (err error) [failretval&0xff==0] = CreateHardLinkW
mksyscall_windows.go 有 doc cmets 可帮助您了解其工作原理。也可以查看zsyscall_windows.go中的go生成代码。
运行go generate
很简单，只需运行：
go generate
示例：
对于您的示例，创建一个名为 win32_windows.go 的文件：
package win32
//go generate go run mksyscall_windows.go -output zwin32_windows.go win32_windows.go

显然，大部分工作是将 Win32 类型转换为 Go 等价物。
请随意浏览 syscall 包 - 他们通常已经定义了您可能感兴趣的结构。
ZOMG 严重吗？？1！ 2 很多工作！
这比手动编写代码要好。并且不需要 CGo！
免责声明：我没有测试上面的代码来验证它确实能达到你想要的效果。使用 Win32 API 本身就是一种乐趣。
