// 读取配置参数 char line[100]; while (fgets(line, sizeof(line), fp)) { int value; if (sscanf(line, "reboot_count=%d", &value) == 1) { reboot_count = value; } else if (sscanf(line, "reboot_status=%d", &value) == 1) { reboot_status = value; } else if (sscanf(line, "reboot_flag=%d", &value) == 1) { reboot_flag = value; } else if (sscanf(line, "image_cnt=%d", &value) == 1) { image_cnt = value; } }在此代码基础上,修改逻辑,将reboot_count,reboot_status,reboot_flag三个参数同时进行更新

好的,你可以按照下面的方式修改代码,以实现同时更新这三个参数:
```c
// 读取配置参数
char line[100];
while (fgets(line, sizeof(line), fp)) {
int value;
if (sscanf(line, "reboot_count=%d", &value) == 1) {
reboot_count = value;
reboot_status = read_reboot_status();
reboot_flag = read_reboot_flag();
} else if (sscanf(line, "reboot_status=%d", &value) == 1) {
reboot_status = value;
reboot_count = read_reboot_count();
reboot_flag = read_reboot_flag();
} else if (sscanf(line, "reboot_flag=%d", &value) == 1) {
reboot_flag = value;
reboot_count = read_reboot_count();
reboot_status = read_reboot_status();
} else if (sscanf(line, "image_cnt=%d", &value) == 1) {
image_cnt = value;
}
}
```
在上面的代码中,我们仍然使用了sscanf函数来读取配置参数。不过,在每一次读取到reboot_count、reboot_status和reboot_flag三个参数时,都会调用相应的读取函数来更新这三个参数的值。例如,在读取到reboot_count参数时,我们调用了read_reboot_status和read_reboot_flag函数来分别读取reboot_status和reboot_flag的值,并将它们更新到相应的变量中。这样,我们就实现了同时更新这三个参数的逻辑。
