C # DllImport : vkCreateInstance 호출시 AccessViolationException

C #에서 Vulkan 래퍼를 만들려고하는데 함수를 호출 할 때 몇 가지 문제가 있습니다. vulkan.h 헤더를 다음과 같이 다시 작성했습니다.

public static class Vk {
    [StructLayout(LayoutKind.Sequential)] public class Instance { }

    public enum Result {
        ...
    }
    public enum StructureType {
        ...
    }

    [StructLayout(LayoutKind.Sequential)] public class ApplicationInfo {
        public StructureType sType;
        public IntPtr pNext;
        public string pApplicationName;
        public uint applicationVersion;
        public string pEngineName;
        public uint engineVersion;
        public uint apiVersion;
    }

    [StructLayout(LayoutKind.Sequential)] public class InstanceCreateInfo {
        public StructureType sType;
        public IntPtr pNext;
        public uint flags_VkInstanceCreateFlags;
        public ApplicationInfo pApplicationInfo;
        public uint enabledLayerCount;
        public string[] ppEnabledLayerNames;
        public uint enabledExtensionCount;
        public string[] ppEnabledExtensionNames;
    }

    [DllImport("vulkan-1.dll", EntryPoint = "vkCreateInstance")]
    public extern static Result CreateInstance(
        InstanceCreateInfo pCreateInfo,
        IntPtr AllocationCallbacks_pAllocator,
        out IntPtr pInstance_Instance);
}

이 함수의 C에서 원래 선언은 다음과 같습니다.

VKAPI_ATTR VkResult VKAPI_CALL vkCreateInstance(
    const VkInstanceCreateInfo*                 pCreateInfo,
    const VkAllocationCallbacks*                pAllocator,
    VkInstance*                                 pInstance);

이제 함수를 호출 할 때 다음과 같이합니다.

Vk.InstanceCreateInfo instance_create_info = new Vk.InstanceCreateInfo();
...

IntPtr hinstance;
Vk.Result result = Vk.CreateInstance(instance_create_info, IntPtr.Zero, out hinstance);   <-- error AccessViolationException

유효한 해결책 인 것 같아서 내 문제가 어디에 있는지 이해하지 못합니다 .StackOverflow : c #에서 pInvoke를 통해 vkEnumeratePhysicalDevices를 호출 할 때 AccessViolationException .

내 IntPtr 힌 스턴스 를 초기화하여 시도했습니다.

Marshal.AllocHGlobal(Marshal.SizeOf<Vk.Instance>());  

또한 Marshal.StructureToPtr (...);을 사용 하여 instance_create_info를 다른 IntPtr로 "변환"하려고했습니다 . 그리고 ref 키워드로 instance_create_info 및 instance 를 전달하려고했습니다 . 분명히 아무것도 효과가 없었습니다.

어떤 생각?

편집하다 :

기본 함수는 다음과 같이 사용됩니다.

//Definition
typedef struct VkApplicationInfo {
    VkStructureType    sType;
    const void*        pNext;
    const char*        pApplicationName;
    uint32_t           applicationVersion;
    const char*        pEngineName;
    uint32_t           engineVersion;
    uint32_t           apiVersion;
} VkApplicationInfo;`

    VkStructureType             sType;

    application_info.pEngineName            = "";

    instance_create_info.sType                      = VK_STRUCTURE_TYPE_INSTANCE_CREATE_INFO;
    instance_create_info.pApplicationInfo           = &application_info;
    instance_create_info.enabledLayerCount          = 0

    instance_create_info.enabledExtensionCount      = 0

VkInstance _instance = nullptr;
assert( !vkCreateInstance( &instance_create_info, nullptr, &_instance ) );
