💫 meson_spifc_drain_buffer(9) 💫

okay so bestie, welcome to the Kernel API Manual — this one's a lil function page and it's honestly iconic in its simplicity. no cap, it's short, but it slaps. let's get into it 🎀

🌸 NAME 🌸

meson_spifc_drain_buffer — copy data from device buffer to memory

like, literally that's the whole gig. data goes from the device's buffer into memory. draining the tank, bestie. 🫗

---

✨ SYNOPSIS ✨

void meson_spifc_drain_buffer (struct meson_spifc *spifc , u8 *buf , int
len );

it returns void, so don't go looking for a return value, there isn't one. she just does the thing 💅

🦋 ARGUMENTS 🦋

• spifc — the Meson SPI device. this is your main character, the whole reason we're here 👑
• buf — the destination buffer. this is where the data lands, the final boss of the copy 🎯
• len — number of bytes to copy. yes queen, tell her exactly how much 🍓

💀 reminder from your girl: this page is short because the function is short. no hidden lore, no secret options, nothing. what you see is what you get, and what you get is a buffer drain. periodt.
