💖 scsw_is_tm(9) 💖

okay so this is a page from the Kernel API Manual, bestie, and it's honestly so short you could read it between classes ✨

🌸 NAME 🌸

scsw_is_tm — the vibe check that tells you if an scsw is a transport mode scsw 🚦

🎀 SYNOPSIS 🎀

int scsw_is_tm (union scsw *scsw );

like, that's it. one function. one argument. she's lowkey minimal and I respect it 💅

🦋 ARGUMENTS 🦋

  • scsw — pointer to scsw. yes, that's the whole description, the manpage is not gonna elaborate, bestie 😭 just know it's a pointer to the scsw you're checking. iconic laziness fr fr.

💜 DESCRIPTION 💜

okay so here's the whole tea ☕ — scsw_is_tm returns non-zero if the specified scsw is a transport mode scsw, and zero otherwise.

that's the entire function. she's a boolean with main character energy 👑 ngl this is the kind of function that just knows and doesn't need to explain herself. you pass the pointer, she tells you yes or no, done. periodt. 🔥

heads up: she gives you non-zero, not necessarily 1 — so don't go comparing her against 1 like it's a guarantee, because it's not 🙈 just treat "truthy" as true and move on.

🌈 SEE ALSO 🌈

this list is long long, so buckle up — same order as the original, no cap 🫶

like I said. whole friend group. the _is_valid_ girlies AND the _is_solicited_ girlies AND the cmd/tm variants all showed up to the function party 🎉 slay.

and that's the whole page, bestie 🍓 she lives in ./arch/s390/include/asm and this edition dropped October 2026 — go read the header file if you want the lore, mwah 💋✨🧚
