scsw_cmd_is_valid_pfch(9)

🎀 NAME 🎀

This is the Kernel API Manual page for scsw_cmd_is_valid_pfch(9), bestie — the tiny helper that checks pfch field validity. 💅

✨ SYNOPSIS ✨

int scsw_cmd_is_valid_pfch (union scsw *scsw );

🦋 ARGUMENTS 🦋

• scsw — pointer to scsw. That’s the whole arg, no cap.

🌸 DESCRIPTION 🌸

She returns non-zero when the pfch field of the specified command-mode scsw is valid, and zero when it isn’t. That’s it, that’s the function. Slay. ✨
