we can test like this:
int main(int argc, char** argv)
{
int ret;
int fd;
int temp, cap, current, vol;
int fd = open("/dev/charge/fakegauge", O_RDRW);
if (fd < 0) {
return -EINVAL；
}
ret = ioctl(fd, BATIOC_TEMPERATURE, (unsigned long)((uintptr_t)(&temp)));
if (ret < 0) {
printf("can not get battery temperature\n");
}
ret = ioctl(fd, BATIOC_CAPACITY, (unsigned long)((uintptr_t)(&cap)));
if (ret < 0) {
printf("can not get battery capacity\n");
}
ret = ioctl(fd, BATIOC_CURRENT, (unsigned long)((uintptr_t)(¤t)));
if (ret < 0) {
printf("can not get battery current\n");
}
ret = ioctl(fd, BATIOC_VOLTAGE, (unsigned long)((uintptr_t)(&vol)));
if (ret < 0) {
printf("can not get battery voltage\n");
}
return ret;
}
