linux编程中接收主函数返回值以及错误码提示

程序A创建子进程,并调用进程B,根据不调用的不同情况,最后显示结果不同. #include <stdio.h> #include <unistd.h> #include <sys/wait.h> #include <sys/types.h> #include <errno.h> int main() { pid_t pid, rpid; int stat; if ((pid = fork()) < 0) { perror("for

linux内核中错误码处理函数

在linux中定义了许多错误码,比如:-ENOMEM, -EINTR等错误码.而这些错误码从本质上来说都是一些负整数而已. 然而在实际的代码过程中,有的函数的返回值是指针类型的,有的是整数类型的. 比如下面这个函数: struct kfifo * kfifo_init() { struct kfifo *kfifo; kfifo = kmalloc(sizeof(struct kfifo), GFP_KERNEL); if( !kfifo ) return -ENOMEM ; } 这个函数要求的

Linux运维之Shell编程------（一）监控MySQL错误码及主从复制同步异常

Linux运维之Shell编程 一.监控MySQL错误码及主从复制同步异常 题目:监控MySQL主从同步是否异常,如果异常,则发送短信或者邮件给管理员.提示:如果没主从同步环境,可以用下面文本放到文件里读取来模拟:阶段1:开发一个守护进程脚本每30秒实现检测一次.阶段2:如果同步出现如下错误号(1158,1159,1008,1007,1062),则跳过错误.阶段3:请使用数组技术实现上述脚本(获取主从判断及错误号部分) 阶段2: #!/bin/bash#CONTACT='[email prote

errno.h 错误码描述.

描述:一般说的Linux源码的目录,默认是基于 /usr/include/ 的. 使用 1 char *strerror(int errnum); 函数打印错误代码的描述.我简单对比了一下,发现描述大体一致,但有些地方, strerror 函数的描述还稍微详细点. 在实际编程中用这一招解决了不少原本看来莫名其妙的问题.比较 麻烦的是每次都要去linux源代码里面查找错误代码的含义,现在把它贴出来,以后需要查时就来这里看了: 实现代码: 1 #include <string.h> //for s

HTTP协议头及错误码详解

通常HTTP消息包括客户机向服务器的请求消息和服务器向客户机的响应消息.客户端向服务器发送一个请求,请求头包含请求的方法.URI.协议版本.以及包含请求修饰符.客户信息和内容的类似于MIME的消息结构.服务器以一个状态行作为响应,相应的内容包括消息协议的版本,成功或者错误编码加上包含服务器信息.实体元信息以及可能的实体内容. Http协议定义了很多与服务器交互的方法,最基本的有4种,分别是GET.POST.PUT.DELETE.一个URL地址用于描述一个网络上的资源,而HTTP中的GET.POS
