cpumask_copy(9)

💅 cpumask_copy(9) ✨

okay so bestie, this page is straight out of the Kernel API Manual, and it’s about the most copy-paste-coded function maybe ever: cpumask_copy. the whole assignment is literally *dstp = *srcp, and honestly? iconic. no cap. 🫶

🌸 NAME 🌸

• cpumask_copy — *dstp = *srcp

✨ SYNOPSIS ✨

void cpumask_copy (struct cpumask *dstp , const struct cpumask *srcp );

one line, zero drama. she’s serving minimalist and we respect it. 💖

🎀 ARGUMENTS 🎀

• dstp — the result. this is where the copy goes, bestie. 💅
• srcp — the input cpumask. the source material, the blueprint, the whole vibe. 🦋
