extcon_set_property_sync(9)

💅 extcon_set_property_sync(9) ✨

okay so this is from the Kernel API Manual and bestie, it's giving "set a property on an external connector, but make it synced" 🫶

---

🌸 NAME 🌸

extcon_set_property_sync — set the property of an external connector, with sync 💫

---

🎀 SYNOPSIS 🎀

int extcon_set_property_sync (struct extcon_dev *edev , unsigned int id , unsigned int prop , union extcon_property_value prop_val );

---

🦋 ARGUMENTS 🦋

• edev — the extcon device, aka the main character of this whole situation 👑
• id — the unique id that points at one specific external connector, no cap, no duplicates
• prop — the property id, telling you which extcon property we're dealing with
• prop_val — the pointer holding the shiny new value of the extcon property 💖

---

🌈 DESCRIPTION 🌈

Heads up, bestie, this part matters: when you're setting the property value of an external connector, the external connector should be attached. Fr fr. Not optional, not a vibe suggestion.

Also, each property has to be included in the list of supported properties according to the extcon type — like, you can't just show up with a property nobody invited to the list 🙈

Returns 0 if it slayed (success), or an error number if it failed 😭
