blkcg_set_fc_appid(9)

🎀 NAME 🎀

okay so bestie, welcome to blkcg_set_fc_appid(9) from the Kernel API Manual ✨ — this one is literally set the fc_app_id field associted to blkcg 💅 (and yeah, “associted” is the spelling in the source; I’m keeping it, no cap 🫶).

✨ SYNOPSIS ✨

int blkcg_set_fc_appid (char *app_id , u64 cgrp_id , size_t app_id_len
);

It’s giving “returns an int” energy 🔥, and the args are laid out exactly like that. Don’t touch the spacing, she’s sensitive 💅.

💅 ARGUMENTS 💅

• app_id — the application identifier 🎀
• cgrp_id — the cgroup id, iconic 🦋
• app_id_len — the size of the application identifier, periodt ✨

👀 SEE ALSO 👀
