pse_control_find_by_id(9)

🎀 pse_control_find_by_id(9) 🎀

okay so this is the Kernel API Manual page for pse_control_find_by_id(9), and it is literally the “find your fave by id” moment. No cap. 💅

🌸 NAME 🌸

pse_control_find_by_id — find pse_control from an id. That’s the whole quest, bestie. 🫶

✨ SYNOPSIS ✨

struct pse_control * pse_control_find_by_id (struct pse_controller_dev
       *pcdev , int id );

This is the signature. Pass the args and let the kernel do its thing. 😌

🧚 ARGUMENTS 🧚

• pcdev — a pointer to the PSE. 🫶
• id — index of the PSE control. ✨

💖 RETURN 💖

You get a pse_control pointer or NULL. The device returned has had a reference added, and the pointer is safe until the user calls pse_control_put to indicate they have finished with it. 🫶

Cleanup era: when you’re done, that’s the pse_control_put moment. Don’t ghost the reference. 💀
