vpif_input_to_subdev(9)

💅 NAME 💅

okay so vpif_input_to_subdev(9) — from the Kernel API Manual — is literally the function that maps input to sub device ✨. that's the whole name vibe, no cap 💖.

✨ SYNOPSIS ✨

the signature is giving exactly this, bestie:

int vpif_input_to_subdev (struct vpif_capture_config *vpif_cfg , struct vpif_capture_chan_config *chan_cfg , int input_index );

🎀 ARGUMENTS 🎀

• vpif_cfg — the global config ptr, aka the big-picture config situation 💖
• chan_cfg — the channel config ptr, the config bestie for the channel 🦋
• input_index — the given input index from application, like the app is pointing at one input and saying “this one” 👑

🌸 DESCRIPTION 🌸

so this function does the lookup of the sub device information for a given input index 🔍. that's the main character move, periodt.

we report all the inputs to application, fr fr. the inputs table also has sub device name for each input — so every input entry is carrying its sub device name info too, iykyk 👑✨.
