使用JSON-C的内存泄漏 [英] Memory Leak Using JSON-C

问题描述

我是JSON-C的新手，请查看我的示例代码，让我知道它会造成任何内存泄漏，如果可以，那么如何释放JSON-C对象.

I am new to JSON-C, Please see my sample code and let me know of it will create any memory leak, if yes then how to free JSON-C object.

    struct json_object *new_obj         = NULL;
    new_obj = json_tokener_parse(strRawJSON);
    new_obj = json_object_object_get(new_obj, "FUU");
    if(NULL == new_obj){
        SYS_OUT("\nFUU not found in JSON");
        return NO;
    }
    new_obj = json_object_object_get(new_obj, "FOO"); // I m re-using new_obj, without free it?  
    if(NULL == new_obj){
        SYS_OUT("\nFOO not found in JSON");
        return NO;
    }
    // DO I need to clean new_obj, if yes then how ??

我是否需要清洁new_obj，如果是，那么如何清洁.有人可以帮助您了解如何进行JSON-C内存管理.

Do I need to clean new_obj, if yes then how. Can some one help to understand how to do memory management JSON-C.

预先感谢

推荐答案

否，只要我们不为json-object显式分配内存，我们就只需要为根对象调用一次json_object_put，这对我有用. .. !!

NO, We need to call json_object_put only once for root object as long as we are not explicitly allocating memory to json-object and this worked for me.....!!
