sclp_sd_file_create(9)

✨ NAME ✨

sclp_sd_file_create — okay so this one adds a sysfs file representing a Store Data entity, and bestie it’s giving kernel-API main character energy. This is the sclp_sd_file_create(9) page from the Kernel API Manual, btw. 🫶

---

🌸 SYNOPSIS 🌸

The signature is literally:

struct sclp_sd_file * sclp_sd_file_create (const char *name , u8 di );

---

🎀 ARGUMENTS 🎀

Two arguments, both iconic:

• name — Name of file. No cap, that’s the whole vibe.
• di — DI value associated with this entity. Iykyk. 💅

---

🦋 DESCRIPTION 🦋

Okay so here’s the tea: this creates a sysfs directory with the given name, located under:

/sys/firmware/sclp_sd/

The files in this directory can be used to access the contents of the Store Data entity associated with DI. Periodt. ✨

It returns a pointer to the resulting sclp_sd_file object on success, and NULL otherwise. The object must be freed by calling kobject_put on the embedded kobject pointer after use. This is not a drill, bestie — after use, call kobject_put on the embedded kobject pointer. 💀💖
