okay so bestie, welcome to the kernel API manual for snd_hda_add_new_path πΈ this one's a little function that lives in the HDA codec world β it parses the path between the NIDs you hand it and adds that path to the path list. short and sweet, no cap π
β¨ SYNOPSIS β¨
struct nid_path * snd_hda_add_new_path (struct hda_codec *codec ,
hda_nid_t from_nid , hda_nid_t to_nid , int anchor_nid );
that's the whole signature, iconically four args deep π«Ά
π ARGUMENTS π
codecβ the HDA codec, the main character ofc πfrom_nidβ the NID where the path starts from, like the beginning of the lore πΈto_nidβ the NID where the path ends at, the destination, the finale β¨anchor_nidβ the anchor indication β and ngl, if you wanna know what that actually means you gotta go readsnd_hda_parse_nid_path, that's the iykyk moment π₯
π¦ DESCRIPTION π¦
so like, if no valid path is found, it returns NULL. that's it, that's the whole description π no valid path = NULL, periodt.
fr fr do NOT forget the NULL case, bestie β always vibe check your return value before you dereference it π

like, that's the entire group chat, every single member accounted for π
and that's a wrap!! this page came straight outta ./sound/hda/codecs, dated October 2026, and it's literally titled snd_hda_add_new_path(9) β slay, go build yourself a path now ππ
