okay so bestie, welcome to the Kernel API Manual β€” this one is short and sweet and it's literally just "read a cell value as a u16". That's the whole vibe. One job. Iconic behavior, honestly.


✨ SYNOPSIS ✨

int nvmem_cell_read_u16 (struct device *dev , const char *cell_id , u16
       *val );

like, look at her. tiny signature, big main character energy πŸŽ€


🌸 ARGUMENTS 🌸

  • dev β€” the struct device * that's asking for the nvmem cell. it's giving "hi yes this is mine, i'm requesting it" 🫢
  • cell_id β€” the name of the nvmem cell you wanna read. const char *, obviously. you gotta know her name to call her πŸ’…
  • val β€” pointer to the output value, type u16 *. this is where the answer lands. it's the little mailbox where your number gets dropped off πŸ“

⭐ RETURN ⭐

0 on success, or a negative errno if things went sideways. no cap β€” check it, bestie, don't just rawdog the return value 😭
