ENUM SDCA_FDL_SET_INDEX_RANGE(9)

🌸 enum sdca_fdl_set_index_range — the Kernel API Manual moment 💅

okay so bestie, welcome to the <pink>Kernel API Manual</pink> page for enum sdca_fdl_set_index_range(9) — yes that's the whole title, we're being formal today 🎀 this is a real one out of the sound subsystem and it is, and I say this with love, extremely short.

✨ NAME ✨

enum sdca_fdl_set_index_range — the column definitions for the UMP SetIndex. that's it, that's the vibe 🦋

🌈 SYNOPSIS 🌈

no cap, this is the entire thing:

enum sdca_fdl_set_index_range {
    SDCA_FDL_SET_INDEX_SET_NUMBER ,
    SDCA_FDL_SET_INDEX_FILE_SET_ID ,
    SDCA_FDL_SET_INDEX_NCOLS

};

literally three constants and a NCOLS sentinel. she's compact, she's iconic, she's giving minimalist main character energy ✨

🫶 Constants 🫶

• SDCA_FDL_SET_INDEX_SET_NUMBER — the docs on this one are -- undescribed --, like the source genuinely did not write anything for it 🙈 no cap, that's all we get.
• SDCA_FDL_SET_INDEX_FILE_SET_ID — also -- undescribed -- 😭 the header file is being mysterious and honestly? respect.
• SDCA_FDL_SET_INDEX_NCOLS — yep, -- undescribed -- too. the classic "count of columns" name is doing all the heavy lifting here, iykyk 💀

bestie note: all three entries literally say -- undescribed -- in the original, so I'm not gonna sit here and invent lore for them. what you see is what you get, fr fr 👑
