counter_alloc(9)

📦 version 7.3.1, in nixpkgs unstable

🎀 NAME 🎀

okay so this is counter_alloc(9) from the Kernel API Manual, and it's literally counter_alloc - allocate a counter_device. bestie, it's giving “first step of counter registration” energy. 💅

✨ SYNOPSIS ✨

struct counter_device * counter_alloc (size_t sizeof_priv );

🍓 ARGUMENTS 🍓

  • sizeof_priv — the size of the driver private data. yes ma'am, that's the number you pass in. 🫶

🦋 DESCRIPTION 🦋

This is part one of counter registration, no cap. The structure is allocated dynamically to ensure the right lifetime for the embedded struct device. iconic lifetime behavior, honestly. ✨

If this succeeds, call counter_put to get rid of the counter_device again. like, clean up after yourself bestie 💖
