XvioReadRingBuffer function

Reads data from a ring buffer into a buffer

Syntax

C++

NTSTATUS XvioReadRingBuffer(
    PXVIO_RING_BUFFER RingBuffer,
    void* Buffer,
    size_t* BytesRead
);

Parameters

PXVIO_RING_BUFFER
Pointer to a ring buffer context. Can be retrieved with XvioGetRingBufferContext or XvioGetRingBufferContextSafe.

void* Buffer
Pointer to a buffer containing the data to be written.

size_t* BytesRead
Pointer to the amount of bytes to read. Also acts as the output for the amount of bytes read.

Return value

Either returns 0x213, 0x214, or a standard NTSTATUS. I believe that 0x213 means there's still more data and that 0x214 means the end of the ring buffer was reached during a read. That being said, I'm not 100% certain on this information.
