STRUCT IIO_DMA_BUFFER_QUEUE_FILEIO(9)

💖 NAME 💖

struct iio_dma_buffer_queue_fileio — the FileIO state for the DMA buffer, bestie. This is the Kernel API Manual entry for struct iio_dma_buffer_queue_fileio(9), and it's giving “tiny struct, very specific job” energy. 🫶

🌸 SYNOPSIS 🌸

struct iio_dma_buffer_queue_fileio {
    struct iio_dma_buffer_block *blocks[2];
    struct iio_dma_buffer_block *active_block;
    size_t pos;
    size_t block_size;
    unsigned int next_dequeue;
    bool enabled;
};

🎀 Members 🎀

• blocks — Buffer blocks used for fileio. It's literally an array of two struct iio_dma_buffer_block * pointers, no cap. 🧚
• active_block — The block being used in read. She's the main character of the read path rn. 👑
• pos — Read offset in the active block. Like a little bookmark for where the read is at. 🔖
• block_size — Size of each block. Gotta know the block math, bestie. 📏
• next_dequeue — Index of the next block that will be dequeued. The queue's next-up energy. ⭐
• enabled — Whether the buffer is operating in fileio mode. It's the on/off vibe check for fileio mode. 💅
