Go 中带有回调的 MiniDumpWriteDump

我试着用Go中的callback来实现MiniDumpWriteDump.

MiniDumpWriteDump人的呼唤:

    callback := syscall.NewCallback(miniDumpCallback)
    var newCallbackRoutine MINIDUMP_CALLBACK_INFORMATION
    newCallbackRoutine.CallbackParam = 0
    newCallbackRoutine.CallbackRoutine = callback
    ret, _, err := miniDumpWriteDump.Call(
        uintptr(processHandle),
        uintptr(processId),
        uintptr(dumpFile),
        uintptr(options),
        0,
        0,
        uintptr(unsafe.Pointer(&newCallbackRoutine)),
    )

Callback功能本身:

func miniDumpCallback(_ uintptr, CallbackInput *MINIDUMP_CALLBACK_INPUT, _ uintptr) uintptr {
    fmt.Println(CallbackInput.ProcessId, CallbackInput.CallbackType)
    return 1
}

Type个定义:

type MINIDUMP_CALLBACK_INPUT struct {
    ProcessId     win32.ULONG
    ProcessHandle win32.HANDLE
    CallbackType  win32.ULONG
    CallbackInfo  uintptr
}

type MINIDUMP_CALLBACK_INFORMATION struct {
    CallbackRoutine uintptr
    CallbackParam   uintptr
}

调用回调后，一些字段会收到正确的数据，但有些字段会得到nonsensical个值.

例如，上面的回调正确地接收CallbackInput的ProcessId字段，但将随机整数接收为CallbackType，而它应该接收MINIDUMP_CALLBACK_TYPE个枚举.

输出:
