DMMP_PATH_GROUP_ARRAY_GET(3)

✨ NAME ✨

dmmp_path_group_array_get — bestie, this one grabs you the pointer array of path groups 💖

It lives in the Device Mapper Multipath API - libdmmp manual, section 3, and the page is literally called dmmp_...ay_get(3) because even man pages get tired of typing 💀

---

🌸 SYNOPSIS 🌸

void dmmp_path_group_array_get (struct dmmp_mpath *dmmp_mp, struct
dmmp_path_group ***dmmp_pgs, uint32_t *dmmp_pg_count);

okay so it takes three things and hands back absolutely nothing (void, we love a low-maintenance king 👑)

---

🎀 ARGUMENTS 🎀

• dmmp_mp — pointer of struct dmmp_mpath. the mpath you're snooping on 🕵️‍♀️ no cap: if this pointer is NULL, your program gets terminated by assert. like, dead. gone. not a vibe.
• dmmp_pgs — output pointer of struct dmmp_path_group pointer array. yep, that's a triple pointer, it's giving inception 🌀 and fr fr, if this pointer is NULL, your program will be terminated by assert.
• dmmp_pg_count — output pointer of uint32_t. it holds the size of the dmmp_pgs pointer array, so you know how many little guys you got 🫶 and yes, if this pointer is NULL, your program will be terminated by assert. all three of them, same energy, no mercy 💅

three pointers, three asserts, zero chill. check your args before you ship, bestie 😭

---

🦋 DESCRIPTION 🦋

Retrieve the path groups of a certain mpath. that's it, that's the whole job, and it does it slayfully ✨

the memory of the output pointer array is held by struct dmmp_mpath, so do not free it — you don't own it, you're just borrowing it, hands off 🙈 the resources get freed when dmmp_mpath_array_free runs, so let that function do its thing and don't be a hero.

---

💜 RETURN 💜

void

it returns nothing. it gives nothing back. it simply is. main character energy, honestly ⭐

so yeah, that's the whole page: dmmp_path_group_array_get from the Device Mapper Multipath API - libdmmp Manual, dated June 2025, sitting pretty in section dmmp_...ay_get(3) 🌈 go forth and retrieve those path groups, bestie, you got this 💅🎀
