scsw_tm_is_valid_eswf(9)

💖 scsw_tm_is_valid_eswf(9) 💖

okay bestie, we're in the Kernel API Manual and this is the page for scsw_tm_is_valid_eswf(9). It's a tiny scsw validity-check moment, and honestly it's giving "short but important." 🦋✨

✨ NAME ✨

scsw_tm_is_valid_eswf — check eswf field validity. That's it, that's the assignment. 💅

🎀 SYNOPSIS 🎀

int scsw_tm_is_valid_eswf (union scsw *scsw );

🌸 ARGUMENTS 🌸

• scsw — pointer to scsw. She's just a pointer, bestie, pointing at the scsw we're checking. 🫶

💜 DESCRIPTION 💜

Return non-zero if the eswf field of the specified transport mode scsw is valid, zero otherwise. No cap: that's the whole function. It's a vibe check for the eswf field, and you get a non-zero answer when it's valid, zero when it's not. ✨
