How to read received data in the sample example on QUIC_STREAM_EVENT_RECEIVE event

[chemsallioua]

I am very very new to this library and my question might sound very stupid:

Regarding the sample example provided by this library, after receiving data over a stream, the QUIC_STREAM_EVENT_RECEIVE event is triggered in the ServerStreamCallback (precisely here)

    case QUIC_STREAM_EVENT_RECEIVE:
        //
        // Data was received from the peer on the stream.
        //
        printf("[strm][%p] Data received\n", Stream);
        break;

my question is:

How to read the received data, where is the reference to the buffer where I can find the received data?

Thank you!

You need to look at the QUIC_STREAM_EVENT* Event payload:

typedef struct QUIC_STREAM_EVENT {
    QUIC_STREAM_EVENT_TYPE Type;
...
        struct {
            /* in */    uint64_t AbsoluteOffset;
            /* inout */ uint64_t TotalBufferLength;
            _Field_size_(BufferCount)
            /* in */    const QUIC_BUFFER* Buffers;
            _Field_range_(0, UINT32_MAX)
            /* in */    uint32_t BufferCount;
            /* in */    QUIC_RECEIVE_FLAGS Flags;
        } RECEIVE;

You'll notice RECEIVE has a several different fields to use. Generally, Buffers and BufferCount will help you get to the actual data.
