LZ4_resetStream(9)

💅 LZ4_resetStream(9) — like, the Kernel API Manual page, bestie

okay so first things first: this is a page from the Kernel API Manual, and the star of the show is LZ4_resetStream(9). yes that's the same name as the file, we love a self-titled moment. 👑

✨ NAME ✨

LZ4_resetStream — init an allocated LZ4_stream_t structure. that's it. that's the whole job. she's a reset button and she's booked and busy. 🎀

---

🦋 SYNOPSIS 🦋

void LZ4_resetStream (LZ4_stream_t *LZ4_stream );

look at her. void return, one pointer in, no drama. icon behavior fr fr. ⭐

---

🌸 ARGUMENTS 🌸

• LZ4_stream — pointer to the LZ4_stream_t structure. that's your little allocated blob of state, and you're handing her over so she can get wiped clean. 🫶

---

💖 DESCRIPTION 💖

so here's the tea 🍓: an LZ4_stream_t structure can be allocated once and then re-used multiple times. like, you do not need to malloc a fresh one every single time, that would be so wasteful and honestly kind of embarrassing.

use this function to init an allocated LZ4_stream_t structure and start a new compression. that's the vibe check: allocated already? cool, now reset her and go off. 💅✨

ngl bestie, the whole point is that you allocate once and reset repeatedly — that's the entire personality of this little function. no cap. 💖

and that's the page!! 🎀 this cutie came out of ./include/linux, dated October 2026, and yeah, the footer says LZ4_resetStream(9) again because she loves a full-circle moment. bye bestie, go reset something responsibly! 🦋💖🌈
