sshp_buf_read_from_fifo(9)

💅 sshp_buf_read_from_fifo(9) — the Kernel API Manual moment

okay bestie, so this is a page from the Kernel API Manual (section 9, kernel-land, very demure, very mindful) and it's about sshp_buf_read_from_fifo — yeah that's a mouthful, iykyk. Let's get into it 🫶

---

✨ NAME ✨

sshp_buf_read_from_fifo — Transfer data from a fifo to the buffer. that's it, that's the whole vibe 💫

---

✨ SYNOPSIS ✨

size_t sshp_buf_read_from_fifo (struct sshp_buf *buf , struct kfifo
*fifo );

like, two pointers in, a size_t out. simple. iconic. no notes 👑

---

🌸 ARGUMENTS 🌸

• buf — The buffer to write the data into. yes bestie, this one's the destination, it's getting the data 🎀
• fifo — The fifo to read the data from. and this one's the source, it's giving the data away 💜

---

🦋 DESCRIPTION 🦋

So what actually happens? It transfers the data contained in the fifo to the buffer, and — this is the key part — it removes it from the fifo. like, it's a move, not a copy. no cap 🔥

This function will try to transfer as much data as possible, and it's limited either by the remaining space in the buffer or by the number of bytes available in the fifo. whichever one runs out first, that's your ceiling. main character energy is maximum effort within constraints ✨

---

🎀 RETURN 🎀

Returns the number of bytes transferred. that's your size_t. that's the receipt. periodt 💅
