代码如下,maxsize,temp_path,o_rdonly有问题呢。。。。。晕死。。。。
- int main(void)
- {
- int fd;
- double temp = 0;
- char buf[MAX_SIZE];
-
- // 打开/sys/class/thermal/thermal_zone0/temp
- fd = open(TEMP_PATH, O_RDONLY);
- if (fd < 0) {
- fprintf(stderr, "failed to open thermal_zone0/temp\n");
- return -1;
- }
-
- // 读取内容
- if (read(fd, buf, MAX_SIZE) < 0) {
- fprintf(stderr, "failed to read temp\n");
- return -1;
- }
-
- // 转换为浮点数打印
- temp = atoi(buf) / 1000.0;
- printf("temp: %.2f\n", temp);
-
- // 关闭文件
- close(fd);
- }
