β¨ extcon_set_state(9) β¨
okay so bestie, we're in the Kernel API Manual today and this one is literally the glow-up moment for external connectors π buckle up, it's short but it matters.
πΈ NAME πΈ
extcon_set_state β set the state of an external connector. that's it, that's the vibe.
π SYNOPSIS π
int extcon_set_state (struct extcon_dev *edev , unsigned int id , bool state );
π¦ ARGUMENTS π¦
edevβ the extcon device itself, the main character of this whole operation πidβ the unique id that points at one specific external connector. like a name tag but for hardware, iykyk π·οΈstateβ the new state of that external connector. the default semantics aretrue: attached /false: detached. sotrue= it's here and thriving,false= it left the group chat π«Ά
π DESCRIPTION π
okay so listen closely because this is the important part: this function sets the state of an external connector without a notification. no ping, no heads-up, no "hey bestie something changed" text. it justβ¦ sets it. silently. π
so if you actually want to synchronize the state of an external connector, you have to useextcon_set_state_syncandextcon_sync. don't come crying to me when nobody gets notified, because I literally warned you π
it returns 0 if success, or an error number if fail. that's the whole mood.
