select_bin(9)

💖 NAME 💖

okay so bestie, welcome to select_bin(9) from the Kernel API Manual — it’s giving “one job, done iconically” 💅.

select_bin selects the bin that should be used to pack the compressed data in a data_vio with other data_vios. That’s literally the assignment, no cap ✨.

✨ SYNOPSIS ✨

here’s the exact signature, character for character, because we do not play about signatures 🫶:

struct packer_bin * select_bin (struct packer *packer , struct data_vio
       *data_vio );

🎀 ARGUMENTS 🎀

two arguments, two little besties:

• packer — the packer. that’s the packer you’re handing over, periodt 💖
• data_vio — the data_vio. that’s the data_vio in question, main character energy for real 🦋
