lwmi_om_hwmon_read(9)

💖 NAME 💖

lwmi_om_hwmon_read — read HWMON sensor data. Also hi, this page comes from the Kernel API Manual — manual name folded in right here near the top like a little name tag 🫶✨

✨ SYNOPSIS ✨

okay so the signature is literally:

       int lwmi_om_hwmon_read (struct device *dev , enum hwmon_sensor_types
       type , u32 attr , int channel , long *val );

🎀 ARGUMENTS 🎀

• dev — device pointer: the device in question, bestie 💅
• type — sensor type: which sensor type we're working with.
• attr — attribute identifier: the attribute identifier, iykyk.
• channel — channel index: the channel index, no cap.
• val — pointer to store value: where the value gets stored 🫶

🦋 DESCRIPTION 🦋

It reads the current sensor values from the hardware through the WMI interface. That's the vibe: hardware sensor data, via WMI. 🔥

🌸 RETURN 🌸

Returns 0 on success, or an error code. Periodt. 💀
