snd_soc_dapm..._source_path(9)

💅 snd_soc_dapm_widget_for_each_source_path 💅

okay so bestie, we're in the Kernel API Manual today and this one is a macro that literally lives in the ALSA SoC DAPM world — it's giving "I crawl the audio graph so you don't have to" energy. no cap. 🎀

✨ NAME ✨

snd_soc_dapm_widget_for_each_source_path — iterates over all paths leading to a widget. that's it, that's the whole vibe. it's a loop-y girlie. 🦋

🌸 SYNOPSIS 🌸

snd_soc_dapm_widget_for_each_source_path (w , p );

literally just those two little args in the parentheses, bestie. copy it exactly, commas and all — do not get creative with the spacing, the preprocessor is watching. 👀

🎀 ARGUMENTS 🎀

• w — the widget. yes, the widget. the main character of this whole operation. 👑
• p — the path iterator variable. this is your little loop buddy that keeps track of where you are on the walk. give it a name, love it, cherish it. 🫶

🦋 SEE ALSO 🦋

• kernel file ./include/sound/soc-dapm.h — go read it, it's got lore 💀
• snd_soc_dapm_widget_for_each_path(9) — the generalist sibling
• snd_soc_dapm_widget_for_each_path_safe(9) — same energy but it won't trip over itself mid-loop (that's the safe part, iykyk)
• snd_soc_dapm_widget_for_each_sink_path(9) — the opposite direction, we stan a balanced graph 🌈

ngl if you're trying to reverse the flow and you landed here, you might actually want the sink one. just saying. 🙈

and that's the whole page, bestie! source and version live over in ./include/sound and this lil beauty is dated October 2026 — so go forth, iterate those source paths, and slay ✨💖 periodt.
