size_t &  count,
_u32  timeout = DEFAULT_TIMEOUT 
)
virtual

Wait and grab a complete 0-360 degree scan data previously received.

The grabbed scan data returned by this interface always has the following charactistics:

1) The first node of the grabbed data array (nodebuffer[0]) must be the first sample of a scan, i.e. the start_bit == 1 2) All data nodes are belong to exactly ONE complete 360-degrees's scan 3) Note, the angle data in one scan may not be ascending. You can use API ascendScanData to reorder the nodebuffer.

Parameters
nodebufferBuffer provided by the caller application to store the scan data
countThe caller must initialize this parameter to set the max data count of the provided buffer (in unit of rplidar_response_measurement_node_t). Once the interface returns, this parameter will store the actual received data count.
timeoutMax duration allowed to wait for a complete scan data, nothing will be stored to the nodebuffer if a complete 360-degrees' scan data cannot to be ready timely.

The interface will return RESULT_OPERATION_TIMEOUT to indicate that no complete 360-degrees' scan can be retrieved withing the given timeout duration.

caller application can set the timeout value to Zero(0) to make this interface always returns immediately to achieve non-block operation.
