💖 iio_dma_buffer_release(9) 💖

okay bestie, welcome to iio_dma_buffer_release(9) from the Kernel API Manual — it’s the final-cleanup bestie of the DMA buffer world ✨

🌸 NAME 🌸

iio_dma_buffer_release — Release final buffer resources 💅

✨ SYNOPSIS ✨

void iio_dma_buffer_release (struct iio_dma_buffer_queue *queue );

🫶 ARGUMENTS 🫶

• queue — Buffer to release. This is the buffer bestie you’re handing over to get released 🎀

🦋 DESCRIPTION 🦋

Okay so here’s the tea: this one frees the resources that can’t yet be freed in iio_dma_buffer_exit. No cap.

It should be called in the buffer’s release callback implementation right before freeing the memory associated with the buffer. Literally the final little cleanup moment before the memory goes bye-bye 😭✨
