LZ4_loadDictHC(9)

okay bestie, this is LZ4_loadDictHC(9) from the Kernel API Manual — and we’re about to load a static dictionary into LZ4_streamHC like it’s our whole personality 💅✨

🌸 NAME 🌸

LZ4_loadDictHC — load a static dictionary into LZ4_streamHC. periodt.

✨ SYNOPSIS ✨

int     LZ4_loadDictHC (LZ4_streamHC_t *streamHCPtr , const char
       *dictionary , int dictSize );

🎀 ARGUMENTS 🎀

• streamHCPtr — pointer to the LZ4HC_stream_t. that’s the stream bestie.
• dictionary — dictionary to load. the main character of this call, honestly.
• dictSize — size of dictionary.

💖 DESCRIPTION 💖

Use this function to load a static dictionary into LZ4HC_stream. Any previous data will be forgotten — only 'dictionary' will remain in memory. Loading a size of 0 is allowed.

so yeah, it’s giving fresh-start energy: previous data? gone. only 'dictionary' stays in memory. and yes, loading a size of 0 is allowed — no drama, no cap 💀✨

🫶 RETURN 🫶

dictionary size, in bytes (necessarily <= 64 KB).

it hands you back the dictionary size, in bytes — and yes, necessarily <= 64 KB, that’s literally the limit on the page, iykyk 🎀
