Members

BaseAddress

The base address of the region of pages.

AllocationBase

The base address of a range of pages in this region. The page is contained within this memory region.

AllocationProtect

The memory protection when the region was initially allocated. This member can be one of the memory protection options, along with PAGE_GUARD or PAGE_NOCACHE, as needed.

__alignment1

A variable for alignment.

RegionSize

The size of the region beginning at the base address in which all pages have identical attributes, in bytes.

State

The state of the pages in the region. This member can be one of the following values.

State	Meaning
MEM_COMMIT 0x1000	Indicates committed pages for which physical storage has been allocated, either in memory or in the paging file on disk.
MEM_FREE 0x10000	Indicates free pages not accessible to the calling process and available to be allocated. For free pages, the information in the AllocationBase, AllocationProtect, Protect, and Type members is undefined.
MEM_RESERVE 0x2000	Indicates reserved pages where a range of the process's virtual address space is reserved without any physical storage being allocated. For reserved pages, the information in the Protect member is undefined.

Protect

The access protection of the pages in the region. This member is one of the values listed for the AllocationProtect member.

Type

The type of pages in the region. The following types are defined.

Type	Meaning
MEM_IMAGE 0x1000000	Indicates that the memory pages within the region are mapped into the view of an image section.
MEM_MAPPED 0x40000	Indicates that the memory pages within the region are mapped into the view of a section.
MEM_PRIVATE 0x20000	Indicates that the memory pages within the region are private (that is, not shared by other processes).

__alignment2

A variable for alignment.
