scsw_pno(9)

okay bestie, welcome to scsw_pno(9) from the Kernel API Manual — she's a tiny function and she's serving exactly what her name says. 💅

🌸 NAME 🌸

scsw_pno — return scsw pno field

✨ SYNOPSIS ✨

u32 scsw_pno (union scsw *scsw );

🎀 ARGUMENTS 🎀

• scsw — pointer to scsw. That's it, that's the whole argument, and she ate. 🫶

💅 DESCRIPTION 💅

okay so scsw_pno returns the value of the pno field of the specified scsw, no cap. And it does this regardless of whether it's a transport mode scsw or a command mode scsw. It's giving equal-opportunity field accessor, and honestly? iconic. ✨
