Recording data

When an application wants to record data, it needs to create a recorder node, add the nodes that it wishes to record to it, and then continuously read data and record it.

The following code creates a depth node and an audio node, and then records their data to a file:

// Initialize context
xn::Context context;
nRetVal = context.Init();
// TODO: check error code

// Create depth generator
xn::DepthGenerator depth;
nRetVal = depth.Create(context);
// TODO: check error code

// Create audio generator
xn::AudioGenerator audio;
nRetVal = audio.Create(context);
// TODO: check error code

// Create recorder
xn::Recorder recorder;
nRetVal = recorder.Create(context);
// TODO: check error code

// Add depth node to recording
nRetVal = recorder.AddNodeToRecording(depth);
// TODO: check error code

// Add audio node to recording
nRetVal = recorder.AddNodeToRecording(audio);
// TODO: check error code

// Start generating
nRetVal = context.StartGeneratingAll();
// TODO: check error code

// Now read data and record it
while (TRUE)
{
    nRetVal = context.WaitAnyUpdateAll();
    // TODO: check error code
    
    nRetVal = recorder.Record();
    // TODO: check error code
}
