验证子线程分配的内存空间在内存映射区

#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>
#include <unistd.h>
#include <sys/types.h>

void *threadFunc(void *arg)
{
    void *ptr = malloc(1000);
    printf("thread heap'addr = %p\n", ptr);

    int i = 3;
    printf("thread stack'addr = %p\n", &i);
    getchar();
}


int main()
{

    pthread_t child;
    pthread_create(&child, NULL, threadFunc, NULL);

    sleep(10000);

    return 0;
}

结果打印
