✨ NAME ✨

okay so bestie, welcome to the Kernel API Manual page for iio_dma_buffer_set_length(9) — and it's literally the DMA buffer set_length callback. 💅 no cap.

🎀 SYNOPSIS 🎀

int iio_dma_buffer_set_length (struct iio_buffer *buffer , unsigned int
       length );

🌸 ARGUMENTS 🌸

• buffer — the buffer you're setting the length for, bestie.
• length — the new buffer length, fresh and ready. ✨

💖 DESCRIPTION 💖
