💅 ccw_device_get_schid(9) — the Kernel API Manual page you didn't know you needed

okay so bestie, listen. this is a page from the Kernel API Manual, and it's about ccw_device_get_schid — literally the little function that hands you a subchannel id. that's it, that's the whole vibe. short page, but we're gonna treat it right. 🎀

✨ NAME ✨

ccw_device_get_schid — obtain a subchannel id 💅

like, you want the id? she's got the id. periodt.

🌸 SYNOPSIS 🌸

void ccw_device_get_schid (struct ccw_device *cdev , struct
subchannel_id *schid );

so it returns void (no return value, she gives, she doesn't take 🙈) and it takes two args. keep those types exactly as they are, no cap — struct ccw_device * and struct subchannel_id *.

🦋 ARGUMENTS 🦋

  • cdev — the device you want to obtain the id for. she's the main character here 👑
  • schid — literally where to fill in the values. that's the spot. the destination. the ~place~ 💖
ngl this is the whole function: you hand it a device, you hand it a place to put stuff, and the values go in there. chef's kiss.
