✨ dmmp_path_group_selector_get ✨

okay bestie, welcome to the Device Mapper Multipath API — libdmmp Manual, and this page is literally just about one lil function that goes and grabs you a path group selector. it's giving very niche, very cute, very demure. let's get into it 💅

---

🌸 NAME 🌸

dmmp_path_group_selector_get — Retrieve path group selector. that's it. that's the whole job. 🎀

---

🦋 SYNOPSIS 🦋

const char * dmmp_path_group_selector_get (struct dmmp_path_group
*dmmp_pg);

look at her. one function. one argument. no drama. ✨

---

💖 ARGUMENTS 💖

• dmmp_pg — a pointer to struct dmmp_path_group. okay so real talk, if this pointer is NULL, your program will be terminated by assert. not "gently nudged". not "warned". terminated. so pls pls pls don't hand her a NULL, bestie 😭💀

---

👑 DESCRIPTION 👑

so the path group selector is the thing that decides which path inside the active path group gets used for the next I/O. that's the whole vibe. it's the main character of "who's driving the next request" energy, and this function is how you find out her name. 🫶

---

🌈 RETURN 🌈

const char *.

that's it, that's the return type, no cap. 💜

---

⭐ quick reminder for the group chat: don't pass NULL to dmmp_pg unless you want your program to just evaporate on the spot. assert does not play. 🙈
