tty_termios_input_baud_rate(9)

💅 tty_termios_input_baud_rate 💅

okay so bestie, welcome to the Kernel API Manual entry for tty_termios_input_baud_rate(9) — yes that's the whole title, it's giving mysterious main character energy because the NAME section is literally just vibes and nothing else 🫶

---

✨ NAME ✨

tty_termios_input_baud_rate — and that's it. that's the whole name section. no description. a total enigma. the manpage said "figure it out" and honestly? iconic 💀

---

🌸 SYNOPSIS 🌸

speed_t tty_termios_input_baud_rate (const struct ktermios *termios );

so it hands you back a speed_t and it takes one thing. slay, short and sweet 🎀

---

🦋 ARGUMENTS 🦋

• termios — the termios structure, bestie. that's the input. it's a const struct ktermios * and it is literally the thing you're pulling a baud rate out of ✨

---

🔥 DESCRIPTION 🔥

okay so the whole point of this function: it converts termios baud rate data into a speed. that's the job. that's the assignment. it reads the baud rate data sitting in the termios and gives you back an actual speed value 💅

⚠️ important caveat time, no cap: you should call this with the termios lock held if this termios is a terminal termios structure. like, don't just rawdog it, hold the lock 🙈

and here's the tea for the driver girlies 🍓: device drivers can call this function, but they should use ->c_[io]speed directly as they are updated. so yeah, you can, but the preferred path is right there in ->c_[io]speed. iykyk ✨

Locking: none — the function itself does no locking, which is exactly why you gotta bring your own lock to the party 🎀
