💖 NAME 💖

okay so bestie, this is scsw_tm_is_valid_stctl(9) from the Kernel API Manual, and its whole job is to check stctl field validity ✨. literally that’s the assignment: is the stctl field valid? this icon tells you, no cap 💅.

✨ SYNOPSIS ✨

the signature is giving exactly this, verbatim:

int scsw_tm_is_valid_stctl (union scsw *scsw );

🫶 ARGUMENTS 🫶

• scsw — pointer to scsw. just a pointer to the scsw in question, bestie 🫶.
