请C语言帮我写一个关于SKF_DigestInit()函数的测试用例，用来测试其准确性和TPS性能

好的，以下是一个简单的关于SKF_DigestInit()函数的测试用例，它可以测试SKF_DigestInit()函数的准确性和TPS性能：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
#include "skf.h" // 假设你已经包含了国密SKF库的头文件

#define MAX_BUFFER_SIZE 1024

int main()
{
    // 初始化国密SKF库
    ULONG rv = SKF_LoadLibrary(NULL);
    if (rv != SAR_OK) {
        printf("Failed to load SKF library. Error code: %08x\n", rv);
        return -1;
    }

    // 获取设备列表
    DEVINFO devList[16];
    ULONG devListSize = sizeof(devList) / sizeof(devList[0]);
    rv = SKF_EnumDev(TRUE, devList, &devListSize);
    if (rv != SAR_OK || devListSize == 0) {
        printf("Failed to enumerate devices. Error code: %08x\n", rv);
        return -1;
    }

    // 打开设备
    HDEV hDev;
    rv = SKF_ConnectDev(devList[0].DevName, &hDev);
    if (rv != SAR_OK) {
        printf("Failed to connect device %s. Error code: %08x\n", devList[0].DevName, rv);
        return -1;
    }

    // 打开应用
    HAPPLICATION hApp;
    rv = SKF_OpenApplication(hDev, "TestApp", &hApp);
    if (rv != SAR_OK) {
        printf("Failed to open application. Error code: %08x\n", rv);
        return -1;
    }

    // 打开会话
    HCONTAINER hContainer;
    rv = SKF_OpenContainer(hApp, "TestContainer", &hContainer);
    if (rv != SAR_OK) {
        printf("Failed to open container. Error code: %08x\n", rv);
        return -1;
    }

    // 初始化摘要计算上下文
    HCRYPTHASH hHash;
    ULONG algID = SGD_SM3;
    rv = SKF_DigestInit(hHash, algID, NULL, hContainer);
    if (rv != SAR_OK) {
        printf("Failed to initialize digest context. Error code: %08x\n", rv);
        return -1;
    }

    // 准备测试数据
    BYTE testData[MAX_BUFFER_SIZE];
    memset(testData, 0x55, sizeof(testData));
    ULONG testDataLen = sizeof(testData);

    // 计时开始
    clock_t startTime = clock();

    // 重复调用SKF_DigestInit()函数进行测试
    int testCount = 10000;
    for (int i = 0; i < testCount; i++) {
        rv = SKF_DigestInit(hHash, algID, NULL, hContainer);
        if (rv != SAR_OK) {
            printf("Failed to initialize digest context. Error code: %08x\n", rv);
            return -1;
        }
    }

    // 计时结束
    clock_t endTime = clock();
    double totalTime = (double)(endTime - startTime) / CLOCKS_PER_SEC;

    // 输出测试结果
    double tps = testCount / totalTime;
    printf("Test completed. Total time: %.3fs, TPS: %.0f\n", totalTime, tps);

    // 关闭会话
    rv = SKF_CloseContainer(hContainer);
    if (rv != SAR_OK) {
        printf("Failed to close container. Error code: %08x\n", rv);
        return -1;
    }

    // 关闭应用
    rv = SKF_CloseApplication(hApp);
    if (rv != SAR_OK) {
        printf("Failed to close application. Error code: %08x\n", rv);
        return -1;
    }

    // 断开设备
    rv = SKF_DisConnectDev(hDev);
    if (rv != SAR_OK) {
        printf("Failed to disconnect device. Error code: %08x\n", rv);
        return -1;
    }

    // 卸载国密SKF库
    rv = SKF_UnloadLibrary();
    if (rv != SAR_OK) {
        printf("Failed to unload SKF library. Error code: %08x\n", rv);
        return -1;
    }

    return 0;
}

这个测试用例会在指定的设备上打开一个应用，打开一个会话，然后重复调用SKF_DigestInit()函数进行测试。测试完成后，它会输出测试的总时间和TPS值。你可以根据需要修改测试数据的大小和重复次数，来测试SKF_DigestInit()函数的准确性和TPS性能。
