This function registers your data buffer, for non-downsampled data, with the

one of these values:

PS4000A_CHANNEL_A ... PS4000A_CHANNEL_H

* buffer, a buffer to receive the data values

bufferLth, the size of the buffer array

segmentIndex, the serial number of the segment to be retrieved

mode, the type of data reduction to use. See Downsampling for
