blkg_conf_init(9)

okay bestie, this page is blkg_conf_init(9) from the Kernel API Manual — and yes, we're getting into blk-cgroup setup energy 🦋

🌸 NAME 🌸

blkg_conf_init — initialize a blkg_conf_ctx 💅

✨ SYNOPSIS ✨

void blkg_conf_init (struct blkg_conf_ctx *ctx , char *input );

🎀 ARGUMENTS 🎀

• ctx — the blkg_conf_ctx to initialize. This is the main-character struct you're setting up, no cap.
• input — the input string. Yep, that's the blkg config input string you're handing over.

💖 DESCRIPTION 💖

Okay so blkg_conf_init initializes ctx, and that initialized ctx can be used to parse the blkg config input string input. Once it's initialized, ctx can be used with blkg_conf_open_bdev and blkg_conf_prep. That's the whole vibe: init first, then those two functions can do their thing. periodt ✨
