前段时间写了个程序，需要做成后台进程。而且出现异常或者到一个时间间隔就要重调。其实这块可以单独拿出来，如果以后遇到什么类似的要求。就可以直接拿去调用真实作业的程序。

int main(int argc, char *argv[])
{
        pid_t pid1, pid2;

        int returnNum = 0;
        int interval  = atoi(ReadConfigFile("Interval1"));     /* 读取配置文件中关于时间
        sprintf(logmsg, "读取配置 Interval = %d", interval);
        Logger(DEBUG, logmsg);

        pid1 = fork();
        if(pid1 == -1)
        {
                ErrRet("转后台进程失败!");
        }
        else if(pid1 == 0)
        {
                do{
                        /* 后台进程 */
                        pid2 = fork();
                        if(pid2 == -1)
                        {
                                ErrRet("启动文件发送进程失败!\n");
                        }
                        else if (pid2 == 0)
                        {
                                /* 调用批量检查模块 */
                                sprintf(logmsg, "PID[%d]调用批量检查模块。",
                                        getpid());
                                Logger(DEBUG, logmsg);
                                batch_check();
                                return 0;
                        }
                        else
                        {
                                sleep(1);
                                pid2 = wait(&returnNum);
                                sprintf(logmsg, "PID[%d]返回[%d]\n",
                                        pid2, returnNum);
                                Logger(DEBUG, logmsg);
                        }
                        sleep(interval);
                        initEnv(GetSysDate(), "suis_msg_send");
                        Logger(DEBUG, "初始化环境");
                }while(returnNum != 9);
        }
        else
        {
                return 0;
        }
}
