This interface represents bytes of memory.

Syntax

IDebugMemoryBytes2 : IUnknown

Notes for Implementers

The debug engine (DE) implements this interface to represent bytes in memory.

Notes for Callers

GetMemoryBytes returns this interface to provide access to system memory. GetMemoryBytes and GetMemoryBytes return this interface to provide access to an object's bytes.

Methods in Vtable Order

The following table shows the methods of IDebugMemoryBytes2.

Method	Description
ReadAt	Reads a sequence of bytes, starting at a given location.
WriteAt	Writes `dwCount` bytes, starting at `pStartContext`.
GetSize	Gets the size, in bytes, of the memory represented by this interface.

Remarks

For properties, an IDebugProperty2 interface representing an array provides an IDebugMemoryBytes2 interface to access the values in that array.

Visual Studio's Memory View calls GetMemoryBytes to retrieve an IDebugMemoryBytes2 interface for accessing system memory. The address to be accessed is obtained by parsing the expression entered as an address into the Memory View and then evaluating the parsed expression using EvaluateSync to get an IDebugProperty2 interface. A call to GetMemoryContext returns the IDebugMemoryContext2 that describes the memory address. This memory context is then passed to ReadAt and WriteAt.
