💖 calipso_cache_invalidate(9) 💖

this page is from the Kernel API Manual, and it's lowkey a one-trick pony in the best way possible ✨. no cap, it's just here to tell you about invalidating the CALIPSO cache, and honestly? we love a focused icon 💅.

✨ NAME ✨

calipso_cache_invalidate — invalidates the current CALIPSO cache, periodt. that's the whole name-section vibe 🎀.

🌸 SYNOPSIS 🌸

void calipso_cache_invalidate (void );

that's it. that's the signature. main character energy with zero extra clutter 🦋.

🎀 ARGUMENTS 🎀

• void — no arguments. literally none. zero. the function said "I take nothing," and honestly? iconic 🫶.

🦋 DESCRIPTION 🦋

okay so calipso_cache_invalidate invalidates and frees any entries in the CALIPSO cache. that's the move, bestie — entries get invalidated and freed, fr fr ✨.

it returns zero on success and negative values on failure. yes, the description really says that 👑

not me side-eyeing the void synopsis while the description talks about return values 😭 that's just what the page says — I'm relaying the lore exactly, no edits, no extra technical claims 🙈.
