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.
Offset (x86) | Offset (x64) | Definition | Remarks |
---|---|---|---|
0x00 | 0x00 |
PVOID StopHandle; |
input |
0x04 | 0x08 |
ULONG Flags; |
input |
0x08 | 0x10 |
ULONG_PTR TotalNumberOfPages; |
output |
Among the Flags, only 0x01 is presently valid and only then if operating on the system partition.
