aa_label_acntsxprint(9)

💖 aa_label_acntsxprint(9) 💖

okay so bestie, this one's from the Kernel API Manual, and it's all about allocating a __counted string buffer and printing a label. it's giving kernel-internals realness, but I got you. 🫶

✨ NAME ✨

aa_label_acntsxprint — allocate a __counted string buffer and print label. that's the whole vibe: make the buffer, print the label. slay. 💅

✨ SYNOPSIS ✨

int aa_label_acntsxprint (char __counted **strp , struct aa_ns *ns ,
       struct aa_label *label , int flags , gfp_t gfp );

🎀 ARGUMENTS 🎀

• strp — the buffer you're writing to. that's where the output goes, bestie.
• ns — the namespace the profile is being viewed from.
• label — the label you're viewing. it is NOT NULL — like, do not come in here with a null label, fr fr. 🚫
• flags — flags that control what label info is printed.
• gfp — the kernel memory allocation type. very kernel-core of it.

🔥 RETURN 🔥

The size of the name written, or the size that would be written if it's larger than the available buffer — that's the return value, periodt. you get the size either way, so you can see what happened. 😭✨
