LZ4_resetStreamHC(9)

💅 LZ4_resetStreamHC — like, the Kernel API Manual girlies know (section 9, bestie)

okay so real talk, this one's a lil kernel API function from the Kernel API Manual, and honestly? it's giving "reset the vibes so the compression can start fresh" and we're obsessed.

✨ NAME ✨

LZ4_resetStreamHC — the glow-up function that inits an allocated LZ4_streamHC_t structure 💖

✨ SYNOPSIS ✨

void LZ4_resetStreamHC (LZ4_streamHC_t *streamHCPtr , int
compressionLevel );

like, that's the whole signature, no cap. void return, two args, she's simple and she serves.

✨ ARGUMENTS ✨

• streamHCPtr — a pointer to the LZ4_streamHC_t structure. yes queen, the pointer. hand her over 🫶
• compressionLevel — okay so the recommended values are between 4 and 9 (that's the sweet spot, highkey), although literally any value between 1 and LZ4HC_MAX_CLEVEL will work. and if you're feeling chaotic: values >LZ4HC_MAX_CLEVEL behave the same as 16. periodt. 🔥

✨ DESCRIPTION ✨

bestie listen — an LZ4_streamHC_t structure can be allocated once and re-used multiple times. that's the whole point, she's reusable, she's sustainable, she's main character energy ✨

use this function to init an allocated LZ4_streamHC_t structure and start a new compression. so like, you don't allocate a new one every time, you just hit reset and go again. iconic behavior, honestly 💅

ngl, this is the "new compression, who dis" button. wipe the slate, keep the memory, slay.
