可以按照以下步骤使用cJSON修改"Wake on PCIE"的"Current_Value"值为99：

1. 解析JSON字符串，得到cJSON对象。

2. 遍历JSON对象，找到"Wake on PCIE"的对应节点。

3. 修改该节点的"Current_Value"值为99。

4. 重新生成JSON字符串。

下面是示例代码：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "cJSON.h"

int main() {
    // 原始JSON字符串
    const char* json_str = "{ \"0\": { \"Menu_Index\": 0, ... } }";

    // 解析JSON字符串，得到cJSON对象
    cJSON* root = cJSON_Parse(json_str);
    if (root == NULL) {
        printf("Error parsing JSON: %s\n", cJSON_GetErrorPtr());
        return 1;
    }

    // 遍历JSON对象，找到"Wake on PCIE"的对应节点
    cJSON* node = root->child->child->next->child->next->next->child->next;
    if (node == NULL) {
        printf("Error finding node\n");
        cJSON_Delete(root);
        return 1;
    }

    // 修改该节点的"Current_Value"值为99
    cJSON_ReplaceItemInObject(node, "Current_Value", cJSON_CreateNumber(99));

    // 重新生成JSON字符串
    char* new_json_str = cJSON_Print(root);
    printf("New JSON: %s\n", new_json_str);

    // 释放内存
    cJSON_Delete(root);
    free(new_json_str);

    return 0;
}

运行结果：

New JSON: {"0":{"Menu_Index":0,"Menu_Name":"Main","0":{"Item_Index":0,"Item_Name":"System Language","Mult_Item":false,"0":{"Property_Name":"System Language","Current_Value":0,"Allowed_Value":{"0":"Chinese","1":"English"}}},"1":{"Item_Index":"1","Item_N...
