nvram_create_partition(9)

💅 nvram_create_partition(9) — the kernel API manual, but make it cute

okay so bestie, welcome to section 9 of the kernel API manual — this is nvram_create_partition, and yes she's a real one ✨

---

🌸 NAME 🌸

nvram_create_partition — literally just create a partition in nvram 🎀 that's it, that's the gig, no cap

---

🦋 SYNOPSIS 🦋

loff_t nvram_create_partition (const char *name , int sig , int req_size
, int min_size );

like… four args, one return type, and a whole lot of nvram potential 💜

---

✨ ARGUMENTS ✨

• name — the name of the partition you're creating 🏷️ pick something cute
• sig — the signature of the partition you're creating 🔏
• req_size — how much data you wanna allocate, in bytes 📏
• min_size — the minimum acceptable size… and heads up: 0 means req_size 👀 (yes that's a little shortcut, she's generous)

---

🧚 DESCRIPTION 🧚

so here's the vibe check 👑 this function returns either a negative error code, or a positive nvram index pointing at the beginning of the data area of the partition you just made. main character energy either way 💅

⚠️ okay this part matters, bestie: if you passed a min_size that's smaller than req_size, then you're on your own for the real size — you gotta query for the actual size yourself after the call, using nvram_partition_get_size 🫶 don't forget, i'm begging 😭
