c生成带缓冲区的临时配置文件，以便以后在代码中使用

Question

我想为我的序列阅读器创建一个临时配置文件 我认为我的代码不是最优的 有没有更好的方法来检测设备？ 有人提示优化我的代码

此配置文件将在稍后读出 用fp = fopen（tempserv，＆＃34; r＆＃34;）;

和unlink（tempserv）;

#include <stdio.h>
#include <string.h>
#include <sys/types.h>
#include <dirent.h>
#include <fcntl.h>

#define MOUSEPATH "/dev/serial/by-id"
/*

*/
#define EASYSTRING "usb-FTDI_FT232R_USB_UART_"

int main (void){

DIR *dir;int i = 1;
struct dirent *ent;
dir = opendir (MOUSEPATH);
char tempserv[] = "/tmp/generate.conf-XXXXXX";
int fd;fd=mkstemp(tempserv);
char tempstr[512];
char devname[62];

if (dir != NULL){

return 0;
