π ieee80211_get_sband_iftype_data β Kernel API Manual, section 9 π
okay so bestie, welcome to ieee80211_g..._iftype_data(9) β yes that's the abbreviated real one, the full name is ieee80211_get_sband_iftype_data and it lives in the Kernel API Manual, section 9. she's a kernel function and she's here to hand you sband data for one specific iftype, and honestly? she ate. π
β¨ NAME β¨
ieee80211_get_sband_iftype_data β literally just returns the sband data for a given iftype. that's it. that's the whole vibe. no cap.
πΈ SYNOPSIS πΈ
const struct ieee80211_sband_iftype_data *
ieee80211_get_sband_iftype_data (const struct ieee80211_supported_band
*sband , u8 iftype );
the way she returns a const struct ieee80211_sband_iftype_data * β const, bestie, she is NOT letting you mess with her data π«Ά
π¦ ARGUMENTS π¦
sbandβ the sband to search for the STA on. this is the thing you're digging through, iykyk πiftypeβ anenum nl80211_iftype. it's the type of interface you're asking about. lowkey the whole point of the call π
β RETURN β
a pointer to struct ieee80211_sband_iftype_data β slay π β or NULL is none found. so like... do a vibe check on that pointer before you dereference it, fr fr π
no results means NULL, so please actually check. she's not gonna hold your hand on this one. π§
okay so this part is literally just the SEE ALSO section and bestie it is long β it's giving "the entire cfg80211 cinematic universe in one list" π but every single one of these is a real cross-reference and we are not skipping a single one. no cap. let's go π
