MEMORY_PARTITION_CONFIGURATION_INFORMATION

The MEMORY_PARTITION_CONFIGURATION_INFORMATION structure (formally _MEMORY_PARTITION_CONFIGURATION_INFORMATION) is produced as output by a successful call to NtManagePartition when given the information class SystemMemoryPartitionInformation (0).

The structure is defined for both 32-bit and 64-bit Windows, but the 32-bit form is useless in practice before Version 1703 because the 32-bit NtManagePartition fails trivially (returning STATUS_NOT_SUPPORTED).

The sizes in the preceding table and the offsets, names and types in the next are from type information in private symbol files that Microsoft has included in downloadable packages of public symbol files and still makes available at the public symbol server.
