openAI兴起，于是拿着之前小组合作的项目（承认优化较差），交给AI试着帮忙优化下

１.功能函数（TCP_SER_INIT）优化

源代码：

int TCP_SER_INIT(int *tcpsocket, const char *ip, const char *port)
{int res, optval = 1;// TCP通信结构体构建struct sockaddr_in ser = {.sin_family = AF_INET,.sin_port = htons((short)atoi(port)),.sin_addr.s_addr = inet_addr(ip),};*tcpsocket = socket(AF_INET, SOCK_STREAM, 0);if (-1 == *tcpsocket){ERR_MSG("socket");return -1;}// 允许端口快速重复使用res = setsockopt(*tcpsocket, SOL_SOCKET, SO_REUSEADDR, &optval, sizeof(optval));if (-1 == res){ERR_MSG("setsockopt");return -1;}res = bind(*tcpsocket, (struct sockaddr *)&ser, sizeof(ser));if (-1 == res){ERR_MSG("bind");return -1;}res = listen(*tcpsocket, 128);if (-1 == res){ERR_MSG("listen");return -1;}printf("等待客户端链接...\n");return 0;
}

优化后代码：

// TCP通信结构体构建
struct sockaddr_in ser = {.sin_family = AF_INET,.sin_port = htons((short)atoi(port)),.sin_addr.s_addr = inet_addr(ip),
};*tcpsocket = socket(AF_INET, SOCK_STREAM, 0);
if (-1 == *tcpsocket)
{ERR_MSG("socket");return -1;
}// 允许端口快速重复使用
res = setsockopt(*tcpsocket, SOL_SOCKET, SO_REUSEADDR, &optval, sizeof(optval));
if (-1 == res)
{ERR_MSG("setsockopt");return -1;
}res = bind(*tcpsocket, (struct sockaddr *)&ser, sizeof(ser));
if (-1 == res)
{ERR_MSG("bind");return -1;
}res = listen(*tcpsocket, 128);
if (-1 == res)
{ERR_MSG("listen");return -1;
}printf("等待客户端链接...\n");
return 0;

反思：

优化前后的差别：优化前，主要出现在每一次操作之后都要判断操作是否成功，返回相应的值；优化后，通过将操作结果判断和返回值放在操作一起，简化了代码，使之更加简洁易读。

２.手动控制线程代码优化

源代码：

void *pthread_manual(void *arg)
{while (1){int which;msg_t *sendmsg = (msg_t *)arg;if (sendmsg->type & LED1_ON){which = 1;ioctl(fd_led1, IO_LED_ON, &which);}if (sendmsg->type & LED1_OFF){which = 1;ioctl(fd_led1, IO_LED_OFF, &which);}if (sendmsg->type & LED2_ON){which = 2;ioctl(fd_led2, IO_LED_ON, &which);}if (sendmsg->type & LED2_OFF){which = 2;ioctl(fd_led2, IO_LED_OFF, &which);}if (sendmsg->type & LED3_ON){which = 3;ioctl(fd_led3, IO_LED_ON, &which);}if (sendmsg->type & LED3_OFF){which = 3;ioctl(fd_led3, IO_LED_OFF, &which);}if (sendmsg->type & BUZZER_ON){ioctl(fd_buzzer, IO_BUZZER_ON);}if (sendmsg->type & BUZZER_OFF){ioctl(fd_buzzer, IO_BUZZER_OFF);}if (sendmsg->type & FAN_ON){ioctl(fd_fan, IO_FAN_ON);}if (sendmsg->type & FAN_OFF){ioctl(fd_fan, IO_FAN_OFF);}if (sendmsg->type & MOTOR_ON){ioctl(fd_motor, IO_MOTOR_ON);}if (sendmsg->type & MOTOR_OFF){ioctl(fd_motor, IO_MOTOR_OFF);}}
}

优化后代码：

    //循环处理每个设备for(int i=0; i<6; i++){which = device[i];if (sendmsg->type & LED1_ON){ioctl(fd_led1, IO_LED_ON, &which);}if (sendmsg->type & LED1_OFF){ioctl(fd_led1, IO_LED_OFF, &which);}if (sendmsg->type & LED2_ON){ioctl(fd_led2, IO_LED_ON, &which);}if (sendmsg->type & LED2_OFF){ioctl(fd_led2, IO_LED_OFF, &which);}if (sendmsg->type & LED3_ON){ioctl(fd_led3, IO_LED_ON, &which);}if (sendmsg->type & LED3_OFF){ioctl(fd_led3, IO_LED_OFF, &which);}if (sendmsg->type & BUZZER_ON){ioctl(fd_buzzer, IO_BUZZER_ON);}if (sendmsg->type & BUZZER_OFF){ioctl(fd_buzzer, IO_BUZZER_OFF);}if (sendmsg->type & FAN_ON){ioctl(fd_fan, IO_FAN_ON);}if (sendmsg->type & FAN_OFF){ioctl(fd_fan, IO_FAN_OFF);}if (sendmsg->type & MOTOR_ON){ioctl(fd_motor, IO_MOTOR_ON);}if (sendmsg->type & MOTOR_OFF){ioctl(fd_motor, IO_MOTOR_OFF);}}}
