-
typedef struct _VSS_DIFF_VOLUME_PROP { VSS_PWSZ m_pwszVolumeName; VSS_PWSZ m_pwszVolumeDisplayName; LONGLONG m_llVolumeFreeSpace; LONGLONG m_llVolumeTotalSpace; } VSS_DIFF_VOLUME_PROP;
m_pwszVolumeName: A null-terminated character string that contains the volume mount name of the volume.
m_pwszVolumeDisplayName: A null-terminated character string that contains one of the mount point paths for the volume. If the volume has no mount points, the string MUST be equal to m_pwszVolumeName.
m_llVolumeFreeSpace: The amount of free space, in BYTEs, on the volume.
m_llVolumeTotalSpace: The total size, in BYTEs, of the volume.
