我有以下代码,我想清理由json_object_new_string().
#include <json/json.h>
#include <stdio.h>
int main() {
/*Creating a json object*/
json_object * jobj = json_object_new_object();
/*Creating a json string*/
json_object *jstring = json_object_new_string("Joys of Programming");
/*Form the json object*/
json_object_object_add(jobj,"Site Name", jstring);
/*Now printing the json object*/
printf ("The json object created: %sn",json_object_to_json_string(jobj));
/* clean the json object */
json_object_put(jobj);
}
生产线是否同时json_object_put(jobj);清洁jobj和jstring?
还是我要一个jstring人一起干净json_object_put(jstring);?

问题2
如果jstring以这种方式将其添加到函数中,会有什么行为?
#include <json/json.h>
#include <stdio.h>
static void my_json_add_obj(json_object *jobj, char *name, char *val) {
/*Creating a json string*/
json_object *jstring = json_object_new_string(val);
/*Form the json object*/
json_object_object_add(jobj,name, jstring);
}
int main() {
/*Creating a json object*/
json_object * jobj = json_object_new_object();
my_json_add_obj(jobj, "Site Name", "Joys of Programming")
/*Now printing the json object*/
printf ("The json object created: %sn",json_object_to_json_string(jobj));
/* clean the json object */
json_object_put(jobj);
}
在jstring这种情况下,它是一个函数的局部变量。是否json_object_put(jobj);会清理jstring(在函数中创建的my_json_add_obj())?
