/**
 * The POWER_INFORMATION_ENERGY_TRACKER_QUERY_OUTPUT structure contains the fixed prefix returned by EnergyTrackerQuery.
 *
 * This prefix has the same layout as POWER_INFORMATION_ENERGY_TRACKER_QUERY_HEADER.
 * Variable-length process records, energy values, tracker configuration, statistics, SIDs and strings
 * follow it and are located by their buffer-relative offsets; TotalSize includes all of these sections.
 * On STATUS_BUFFER_TOO_SMALL, a buffer of at least 0x0C bytes receives Signature, HeaderSize = 0,
 * and the required TotalSize. The remaining fields are valid only after a successful query.
