💾 nvmem_device_cell_write(9) 💾

okay bestie, welcome to the Kernel API Manual — yes that's the manual name, we're being official today 💅 — and today's main character is nvmem_device_cell_write, the lil function that writes a cell to a given nvmem device. slay.

✨ NAME ✨

nvmem_device_cell_write — write a cell to a given nvmem device. that's it, that's the whole vibe. 🎀

🌸 SYNOPSIS 🌸

int nvmem_device_cell_write (struct nvmem_device *nvmem , struct
nvmem_cell_info *info , void *buf );

she takes three things and returns an int, no cap. 🦋

💖 ARGUMENTS 💖

  • nvmem — the nvmem device you're writing to. the target. the destination. the one getting the glow-up. ✨
  • info — the nvmem cell info that's getting written. it's giving "the blueprint". 🎀
  • buf — the buffer that gets written into the cell. the actual payload, the moment, the content. 💅

🔥 RETURN 🔥

she hands back the length of bytes written — or, if things go sideways, a negative error code on failure. so like… positive int = we ate 🍓, negative int = 😭. check it, always. fr fr.

ngl bestie, do not ignore the negative return value, that's the whole point of it being there 🙈
