MEMORY_PARTITION_PAGE_COMBINE_INFORMATION

The MEMORY_PARTITION_PAGE_COMBINE_INFORMATION structure both provides input for and receives output from NtManagePartition when given the information class SystemMemoryPartitionCombineMemory.

The MEMORY_PARTITION_PAGE_COMBINE_INFORMATION structure is 0x0C or 0x18 bytes in 32-bit and 64-bit Windows, respectively. Note, however, that the 32-bit form is useless in practice since the 32-bit NtManagePartition fails as STATUS_NOT_SUPPORTED.

Among the Flags, only 0x01 is presently valid and only then if operating on the system partition.
