media_pipeli..._each_entity(9)

💅 media_pipeli..._each_entity(9)

okay so this is media_pipeli..._each_entity(9) from the Kernel API Manual, and it’s giving “walk the whole media pipeline, bestie” energy. No cap, every detail is staying in here. ✨

🌸 NAME 🌸

media_pipeline_for_each_entity — iterate on all entities in a media pipeline 🌀

🩷 SYNOPSIS 🩷

media_pipeline_for_each_entity (pipe , iter , entity );

🫶 ARGUMENTS 🫶

• pipe — the pipeline 💫
• iter — the iterator (struct media_pipeline_entity_iter) 🎀
• entity — the iterator entity 👑

🌸 DESCRIPTION 🌸

okay so media_pipeline_for_each_entity iterates on all entities in a media pipeline. The vibe check is strict: this is only valid after the pipeline has been built with media_pipeline_start and before it gets destroyed with media_pipeline_stop 🚨

Truly do not skip the iterator admin, bestie: the iterator must be initialized with media_pipeline_entity_iter_init before iteration, and destroyed with media_pipeline_entity_iter_cleanup after — including in code paths that break from the loop 😭 That cleanup is not optional, iykyk.
