seq_put_decimal_ull_width(9)

💅 seq_put_decimal_ull_width(9) — from the Kernel API Manual, bestie ✨

okay so real talk, this one lives in the Kernel API Manual and it's lowkey a little icon, let me tell you everything 🫶

---

🌸 NAME 🌸

seq_put_decimal_ull_width — a helper routine for putting decimal numbers without the rich format of printf(). and like, only unsigned long long is supported, periodt 💅

---

✨ SYNOPSIS ✨

void seq_put_decimal_ull_width (struct seq_file *m , const char
*delimiter , unsigned long long num , unsigned int width );

---

🎀 ARGUMENTS 🎀

• m — the seq_file that identifies the buffer you're writing your data into, iykyk 🦋
• delimiter — a string that gets printed before the number. it's giving opening act energy ✨
• num — the number. that's it. that's the whole vibe 🔢
• width — a minimum field width, so your numbers stay looking cute and aligned 💅

---

🌈 DESCRIPTION 🌈

so this routine will put strlen(delimiter) + number into seq_filed 💖

and the way that it's very quick when you show lots of numbers?? obsessed. genuinely main character energy for number-heavy output 🔥

but ngl, in usual cases it will be better to use seq_printf. it's easier to read. fr fr, no cap 😭

like, speed is great and all, but readability is also a vibe. choose wisely bestie 🫶
