tty_get_char_size(9)

💖 tty_get_char_size(9) 💖

okay so bestie, welcome to the tty_get_char_size(9) page — it's a Kernel API Manual moment, and honestly it's a little icon. tiny function, big "i know my termios" energy. let's get into it ✨

---

🌸 NAME 🌸

tty_get_char_size — get size of a character 🎀

like, the size. of a character. that's the whole vibe. she's not complicated and that's why we love her 💅

---

🦋 SYNOPSIS 🦋

unsigned char tty_get_char_size (unsigned int cflag );

no cap, that's the whole signature. one argument, and she returns an unsigned char. short and slay 🔥

---

👑 ARGUMENTS 👑

• cflag — the termios cflag value 🫶 this is the thing you hand over, and she's gonna go look at its CSIZE setting to figure out what's tea.

---

⭐ RETURN ⭐

she returns the size (in bits) of a character, and that size depends on what cflag's CSIZE setting is set to 💖 that's it, that's the return. bits. not bytes, bestie — bits, iykyk 🌈
