💅 memdup(9) — Kernel API Manual, bestie edition 🎀

okay so welcome to the memdup page, part of the Kernel API Manual ✨ this one's short and sweet and honestly? iconic for it. no cap.

🌸 NAME 🌸

memdup — duplicate region of memory 🫶

that's it. that's the whole job. it duplicates a region of memory. lowkey the most well-adjusted function on the block.

✨ SYNOPSIS ✨

void * memdup (const void *src , size_t len );

look at her. returns a void *, takes exactly two things, no drama, no surprises. main character energy fr fr 💜

🦋 ARGUMENTS 🦋

  • src — memory region to duplicate. like, the actual memory you want copied. hand it over 💌
  • len — memory region length. how much of it we're talking about. the size, the length, the whole vibe check of how many bytes we're duplicating 📏
ngl both of these are mandatory in spirit — src is what, len is how much. don't mix them up bestie 😭
