elf文件解析器_elf文件下载

elf文件解析器_elf文件下载前两天网上投递了简历,面试了一家C++公司,然后对面负责人给我发了一份笔试题,题目是:请写出一个ELF文件解析器,需要能打印出所有segments和sections,并列出每个section和segment的映射关系。首先了解elf是什么,它的结构是怎么样的,然后去读一下别人的源码,读懂之后,自己开始编码。源码如下(”elf.h”头文件见后文),它会报warning,但是貌似不太影…

前两天网上投递了简历,面试了一家C++公司,然后对面负责人给我发了一份笔试题,题目是:

请写出一个ELF文件解析器, 需要能打印出所有segmentssections,并列出每个sectionsegment的映射关系。

首先了解elf是什么,它的结构是怎么样的,然后去读一下别人的源码,读懂之后,自己开始编码。

源码如下(”elf.h” 头文件见后文),它会报warning,但是貌似不太影响最后结果:

#include<stdlib.h>
#include<stdio.h>
#include "elf.h"

int main(int argc, char* argv[])

        exit(0);
    }

    // 打开文件
    FILE *fp;
    fp = fopen(argv[1], "r");
    if (NULL == fp)
    {
        printf("fail to open the file");
        exit(0);
    }

    // 解析head
    Elf64_Ehdr elf_head;
    int shnum, a;

    // 读取 head 到elf_head
    a = fread(&elf_head, sizeof(Elf64_Ehdr), 1, fp);
    if (0 == a)
    {

  • kafka零拷贝原理_通俗易解中的解是什么意思

    kafka零拷贝原理_通俗易解中的解是什么意思Kafka之所以那么快,其中一个很大的原因就是零拷贝(Zero-copy)技术,零拷贝不是kafka的专利,而是操作系统的升级,又比如Netty,也用到了零拷贝。下面我就画图讲解零拷贝,如果对你有帮助请点个赞支持。传统IOkafka的数据是要落入磁盘的,那么必然牵扯到磁盘的IO,传统磁盘IO又叫缓存IO,效率是很低的,那么为什么效率低呢?我们先来粗略讲讲操作系统的知识。用户空间以及内核空间的概念:我们知道现在操作系统都是采用虚拟存储器。那么对32位操作系统而言,它的寻址空间(虚拟存储空间)
