Standard GNOME way to handle sysfs changes?

[Xoliper]

Hi, im trying to add battery charge threshold feature to gnome-control-center application, and i wonder if there is any standard (GNOME) way to handle parameters exposed in sysfs?

I will be using /sys/class/power_supply/BATT/charge_control_end_threshold file to set the threshold on kernels >= 5.4.
I assume that i can access this subsystem via libudev, but the question is - “is this the way” Or should i just use plain old write() ?

//EDIT 1
Second question, maybe i should just handle gsettings [key] state inside gnome-control-center app and create daemon + new application for handling this changes and in that way i will not pollute gnome-control-center with libudev?

//EDIT 2

This snippet i wrote is doing great, and could be converted into something like “gnome-battery-threshold-manager” along with systemd daemon which will be managed by gnome-control-center:

    struct udev *udev;
    struct udev_enumerate *enumerate;
    struct udev_list_entry *devices, *dev_list_entry;
    struct udev_device *dev;
    const char new_value[3] = {'8','0','\0'};
    
    /* Create the udev object */
    udev = udev_new();
    if (!udev) {
        printf("Can't create udev\n");
        exit(1);
    }
    
    /* Create a list of the devices in the 'power_supply' subsystem. */
    enumerate = udev_enumerate_new(udev);
    udev_enumerate_add_match_subsystem(enumerate, "power_supply");
    udev_enumerate_scan_devices(enumerate);
    devices = udev_enumerate_get_list_entry(enumerate);
    
    //Go through all supported devices
    udev_list_entry_foreach(dev_list_entry, devices) {
        
        const char* path = udev_list_entry_get_name(dev_list_entry);
        dev = udev_device_new_from_syspath(udev, path);
        
        //Check if supported this device supports this attribute by reading it.
        const char* ccet = udev_device_get_sysattr_value(dev, "charge_control_end_threshold");
        if(ccet != nullptr){
            //udev_device_set_sysattr_value needs evelated privileges.
            udev_device_set_sysattr_value(dev, "charge_control_end_threshold", &new_value[0]);
        }
    }
    /* Free the enumerator object */
    udev_enumerate_unref(enumerate);
    udev_unref(udev);

//EDIT 3
Ok, so i noticed that GNOME have their own version of libudev, called gudev and this is the native way to handle sysfs access. This topic can be closed.
