π« cfg80211_sinfo_alloc_tid_stats β the kernel API manual, bestie edition β¨
okay so real talk, this is a page from the Kernel API Manual (section 9, iykyk) and it's about cfg80211_sinfo_alloc_tid_stats. say that five times fast, I dare you. π
It does exactly one iconic thing and it does it well: it allocates per-tid statistics. that's it. that's the whole vibe. no cap.
π NAME π
cfg80211_sinfo_alloc_tid_stats β allocate per-tid statistics.
like, literally just allocate them. per tid. stats. we love a function that knows what it wants. π¦
πΈ SYNOPSIS πΈ
int cfg80211_sinfo_alloc_tid_stats (struct station_info *sinfo , gfp_t
gfp );
so it takes a struct station_info * and a gfp_t, and it hands you back an int. simple. clean. main character energy. β¨
π ARGUMENTS π
sinfoβ the station information. that's thestruct station_info *bestie, the thing you're stuffing the stats into. π«Άgfpβ allocation flags. thegfp_t. this is where you tell the kernel how you'd like the memory allocated, and it's a whole thing, but you already knew that. π
β RETURN β
0on success. slay. π- Non-zero on error. not slay, but at least you know. π
okay and that's genuinely it for part one β keep scrolling, there's more coming, don't go anywhere π
β¨ SEE ALSO β¨
okay bestie, this is the part where the page name-drops literally every other page in the cfg80211 cinematic universe π and there are a lot of them, no cap. every single cross-reference is here β grouped so it actually makes sense β so grab a snack and let's go π
