Gets a waveform group.
#include "Ltdic.h"
L_UINT16 LDicomDS::GetWaveformGroup(uIndex, pWaveformGroup)
Zero-based index of the group to be retrieved. As an example, if there are three waveform groups, use an index of 2 to retrieve the third group.
Pointer to a class which holds the waveform group attributes and data.

In DICOM, a waveform consists of one or more multiplex groups, each encoded into an item in the "Waveform Sequence" (5400,0100). Use this function to extract the specified multiplex group.
This function populates the object pointed to by pWaveformGroup with the multiplex group attributes and for each channel in the group, adds a new channel by calling LDicomWaveformGroup::AddChannel.
This function fails and returns DICOM_ERROR_NULL_PTR if pWaveformGroup is NULL.
This is the main function for extracting waveforms from a DICOM dataset. Once pWaveformGroup is populated you can call the functions defined either by LDicomWaveformGroup or LDicomWaveformChannel, providing you comprehensive DICOM waveform support.
Win32, x64
For an example, refer to LDicomWaveformChannel::SetChannelSamples8.
