///////////////////////////////////////////////////////////////////////////////
//
// The WINIBIO_SENSOR_CONTEXT structure is privately-defined by each
// Sensor Adapter. Its purpose is to maintain any information that
// should persist across Sensor Adapter API calls.
//
// The Adapter allocates and initializes one of these structures in its
// 'Attach' routine and saves its address in the Pipeline->SensorContext
// field.
//
// The Sensor Adapter's 'Detach' routine cleans up and deallocates the
// structure and sets the PipelineContext->SensorContext field to NULL.
//
///////////////////////////////////////////////////////////////////////////////
typedef struct _WINIBIO_SENSOR_CONTEXT {
//
// The following fields illustrate the kind of information
// the Sensor Adapter needs to keep in this structure:
//
// SampleBuffer - A pointer to the most-recently-captured
// data sample from the sensor device.
//
// SampleSize - Count of the number of bytes in the
// sample buffer.
//
PWINBIO_BIR SampleBuffer;
SIZE_T SampleSize;
