trace_seq_bitmask(9)

📦 version 7.3.1, in nixpkgs unstable

💅 trace_seq_bitmask — the Kernel API Manual glow-up

okay bestie, welcome to trace_seq_bitmask</p> from the Kernel API Manual — section 9, kernel devs only, no cap ✨

🌸 NAME 🌸

trace_seq_bitmask — write a bitmask array in its ASCII representation

like, it takes your bits and turns them into a cute little string of characters. it's giving translator energy 🦋

🎀 SYNOPSIS 🎀

void trace_seq_bitmask (struct trace_seq *s , const unsigned long *maskp
, int nmaskbits );

so you're calling trace_seq_bitmask, you're passing it a struct trace_seq *s, a const unsigned long *maskp, and an int nmaskbits. it returns void, which means it literally gives nothing back — main character who doesn't do returns 💅

✨ ARGUMENTS ✨

  • s — the trace sequence descriptor. that's the destination babe, the place where the output goes 🫶
  • maskp — points to an array of unsigned longs that represent a bitmask. so it's a pointer, to an array, of unsigned longs, that's the bitmask. yes all of that. iykyk 🧚
  • nmaskbits — the number of bits that are valid in maskp. like how many of them actually count. the rest? not invited to the party 🙈

💖 DESCRIPTION 💖

Writes a ASCII representation of a bitmask string into s.

that's it, that's the whole vibe. bitmask goes in, ASCII representation comes out, and it lands in s. iconic behavior honestly 👑

⚠️ quick note bestie: the original says "a ASCII" not "an ASCII". we do not fix the manpage grammar, we simply report it. heritage 💀
