帮我写一个WFP 的demo

好的，我可以为您提供一个 WFP 的 demo，您可以参考以下代码：

#include <windows.h>
#include <stdio.h>
#include <stdlib.h>
#include <wfp.h>

#pragma comment(lib, "Fwpkclnt.lib")

int main(int argc, char* argv[])
{
FWPM_SESSION session = { };
FWPM_FILTER filter = { };
FWPM_FILTER_CONDITION filterConditions[1] = { };
FWPM_PROVIDER provider = { };
FWPM_SUBLAYER subLayer = { };
HANDLE engineHandle = NULL;
UINT64 filterId = ;
DWORD errorCode = ERROR_SUCCESS;

// 初始化 WFP 引擎
errorCode = FwpmEngineOpen(NULL, RPC_C_AUTHN_WINNT, NULL, &session, &engineHandle);
if (errorCode != ERROR_SUCCESS)
{
printf("Failed to open WFP engine. Error code: %d\n", errorCode);
return -1;
}

// 创建 WFP 提供程序
provider.displayData.name = L"My WFP Provider";
provider.displayData.description = L"Demo WFP Provider";
provider.providerKey = (GUID) { x12345678, x1234, x1234, { x12, x34, x12, x34, x12, x34, x12, x34 } };
errorCode = FwpmProviderAdd(engineHandle, &provider, NULL);
if (errorCode != ERROR_SUCCESS)
{
printf("Failed to add WFP provider. Error code: %d\n", errorCode);
FwpmEngineClose(engineHandle);
return -1;
}

// 创建 WFP 子层
subLayer.displayData.name = L"My WFP SubLayer";
subLayer.displayData.description = L"Demo WFP SubLayer";
subLayer.subLayerKey = (GUID) { x12345678, x1234, x1234, { x12, x34, x12, x34, x12, x34, x12, x34 } };
subLayer.weight = FWP_EMPTY;
errorCode = FwpmSubLayerAdd(engineHandle, &subLayer, NULL);
if (errorCode != ERROR_SUCCESS)
{
printf("Failed to add WFP sublayer. Error code: %d\n", errorCode);
FwpmProviderDeleteByKey(engineHandle, &provider.providerKey);
FwpmEngineClose(engineHandle);
return -1;
}

// 创建 WFP 过滤器条件
filterConditions[].fieldKey = FWPM_CONDITION_IP_REMOTE_ADDRESS;

// 创建 WFP 过滤器
filter.providerKey = provider.providerKey;

filter.action.type = FWP_ACTION_BLOCK;
filter.weight.type = FWP_EMPTY;
filter.filterCondition = filterConditions;
filter.numFilterConditions = ARRAYSIZE(filterConditions);
errorCode = FwpmFilterAdd(engineHandle, &filter, NULL, &filterId);
if (errorCode != ERROR_SUCCESS)
{
printf("Failed to add WFP filter. Error code: %d\n", errorCode);
FwpmSubLayerDeleteByKey(engineHandle, &subLayer.subLayerKey);
FwpmProviderDeleteByKey(engineHandle, &provider.providerKey);
FwpmEngineClose(engineHandle);
return -1;
}

// 关闭 WFP 引擎
FwpmFilterDeleteById(engineHandle, filterId);

return ;
