sysfs_merge_group(9)

💖 NAME 💖

okay bestie, welcome to the sysfs_merge_group(9) page from the Kernel API Manual — and this function is literally here to merge files into a pre-existing named attribute group. that's the whole vibe. 🫶

✨ SYNOPSIS ✨

int sysfs_merge_group (struct kobject *kobj , const struct
       attribute_group *grp );

🎀 ARGUMENTS 🎀

• kobj — the kobject containing the group. like, the main character container. 👑
• grp — the files to create and the attribute group they belong to. it's giving “here are the files, here's their group, make it happen.” ✨

🌸 DESCRIPTION 🌸

so this function returns an error if the group doesn't exist, the .name field is NULL, or any of the files already exist in that group — and in that case, none of the new files are created. no partial slay, no sneaky leftovers. 💅

no cap: if any of those conditions hits, you get an error and the new files just don't get made. periodt. 🫶
