💖 dmmp_context_userdata_set 💖

okay bestie, welcome to the Device Mapper Multipath API — this is a libdmmp manual page and honestly? it's a lil cutie. short, sweet, does exactly one thing. let's get into it ✨

---

✨ NAME ✨

dmmp_context_userdata_set — Set user data pointer. 🎀

that's it. that's the whole job. she sets a pointer. iconic behavior honestly 💅

---

🌸 SYNOPSIS 🌸

void dmmp_context_userdata_set (struct dmmp_context *ctx, void
*userdata);

look at her. two args, no return. minimalism queen 👑

---

🦋 ARGUMENTS 🦋

• ctx — this is a pointer of 'struct dmmp_context'. now listen, bestie, this is the important part: if this pointer is NULL, your program will be terminated by assert. like, full-on yeeted. not a cute little error message, an assert. so pls don't be passing NULL unless you're into that 💀
• userdata — pointer of user defined data. it's your data. you defined it. you brought it here. you're the main character of this pointer 🫶

---

🌈 DESCRIPTION 🌈

so what does she actually do? she stores that user data pointer into 'struct dmmp_context'. that's it. pointer goes in, pointer lives there now. no copying, no transforming, no drama — just vibes and storage ✨

---

⭐ RETURN ⭐

void

yeah. nothing comes back. she gives nothing and takes nothing (except your pointer) 😌

---

ngl this is one of those functions that's like, five seconds of work but you still need the docs to exist, and honestly? respect. fr fr 💜

and that's the whole page, bestie!! 🎀 dmmp_context_userdata_set from the libdmmp manual, dated June 2025, and if you ever see dmmp_...ta_set(3) floating around in a header or a cross-reference, that's just her nickname when the terminal's being a lil shy about truncating things 🙈 slay, go forth and set your userdata 🦋✨
