✨ iio_dma_buffer_exit 💅

okay so bestie, welcome to iio_dma_buffer_exit(9) — that's the kernel API manual page, and yes we're reading manpages together now, it's giving study date energy 🎀

🌸 NAME 🌸

iio_dma_buffer_exit — cleanup DMA buffer queue 🧹✨

💖 SYNOPSIS 💖

void iio_dma_buffer_exit (struct iio_dma_buffer_queue *queue );

🦋 ARGUMENTS 🦋

  • queue — the buffer you're cleaning up, bestie. that's the one. 🫶

🔥 DESCRIPTION 🔥

so here's the tea ☕ — once this function has fully completed, it is safe to free any resources that are associated with the buffer and are accessed inside the callback operations.

like, no cap, that's the whole promise. after iio_dma_buffer_exit is done doing its thing, you're cleared to free those callback-accessed resources. periodt. 👑

lowkey important: the safety only kicks in after the function has completed — don't be out here freeing stuff early, that's not the vibe 😭
