IDkmGPUMemoryOperation.ReadMemory Method

Definition

Namespace:

Microsoft.VisualStudio.Debugger.ComponentInterfaces

Assembly:

Microsoft.VisualStudio.Debugger.Engine.dll

Package:

Microsoft.VisualStudio.Debugger.Engine v17.8.1101801

Read the memory of the target GPU process. The method is on DkmGPUComputeThread because it may read thread local memory, group shared memory or global memory.

C++

public:
 int ReadMemory(Microsoft::VisualStudio::Debugger::GPU::DkmGPUComputeThread ^ computeThread, System::UInt64 address, System::UInt64 instructionPointer, Microsoft::VisualStudio::Debugger::DkmReadMemoryFlags flags, cli::array <System::Byte> ^ buffer);

Parameters

computeThread

DkmGPUComputeThread

[In] DkmGPUComputeThread represents a compute thread running in the GPU target process.

address

UInt64

[In] The address from which to read the target GPU process's memory.

instructionPointer

UInt64

[In] The instruction pointer where to resolve address to register location.

flags

DkmReadMemoryFlags

[In] Flags controlling the behavior of DkmProcess.ReadMemory and DkmProcess.ReadMemoryString.

buffer

Byte[]

[In,Out] A buffer that receives the contents from the address space of the target process. On failure, the content of this buffer is unspecified.

Returns

Int32

[Out] Indicates the number of bytes read from the target GPU process. If DkmReadMemoryFlags.AllowPartialRead is clear, on success this value will always be exactly equal to the input size. If DkmReadMemoryFlags.AllowPartialRead is specified, on success, this value will be greater than zero.
