initialize_compressed_block(9)

okay so welcome to the initialize_compressed_block(9) page from the Kernel API Manual, bestie 💖 this one is short and sweet, and yes, we're keeping every detail.

💅 NAME

initialize_compressed_block — initialize a compressed block, periodt. ✨

🛠️ SYNOPSIS

void initialize_compressed_block (struct compressed_block *block , u16
size );

🎀 ARGUMENTS

• block — the compressed block to initialize. that's the one getting the glow-up 💅
• size — the size of the agent's fragment. yes ma'am, just the size 🎀

🌸 DESCRIPTION

This method initializes the compressed block in the compressed write agent. the compressor already put the agent's compressed fragment at the start of the compressed block's data field, so it needn't be copied — literally why would we copy it, bestie? 😭 So all we need do is initialize the header and set the size of the agent's fragment. that's it, that's the whole vibe ✨
