DkmProcess.AllocateVirtualMemory(UInt64, Int32, Int32, Int32) Method

Definition

Namespace:

Microsoft.VisualStudio.Debugger

Assembly:

Microsoft.VisualStudio.Debugger.Engine.dll

Package:

Microsoft.VisualStudio.Debugger.Engine v17.8.1101801

Reserves and/or commits a region of memory within the virtual address space of the target process. The function initializes the memory it allocates to zero, unless MEM_RESET is used. For additional information, see the VirtualAlloc Win32 API in MSDN.

Public Function AllocateVirtualMemory (Address As ULong, Size As Integer, AllocationType As Integer, PageProtection As Integer) As ULong

Parameters

Address

UInt64

[In] Address within the target process where the memory should be committed or reserved. This value is typically zero, in which case the system chooses an address.

Size

Int32

[In] The size of the region of memory to allocate, in bytes. The system will automatically round up to the next page boundary.

AllocationType

Int32

[In] Indicates the type of allocation to perform. This is typically MEM_COMMIT | MEM_RESERVE (0x3000) which reserves and commits an allocation in one step.

PageProtection

Int32

[In] The memory protection for the region of pages to be allocated. If the pages are being committed, you can specify any one of the memory protection constants (ex: PAGE_READWRITE, PAGE_EXECUTE).

Returns

UInt64

[Out] Base address of the allocated region of pages.
