IWDFMemory interface (wudfddi.h)
[Warning: UMDF 2 is the latest version of UMDF and supersedes UMDF 1. All new UMDF drivers should be written using UMDF 2. No new features are being added to UMDF 1 and there is limited support for UMDF 1 on newer versions of Windows 10. Universal Windows drivers must use UMDF 2. For more info, see Getting Started with UMDF.]
The IWDFMemory interface exposes the framework memory object that provides access to a memory block.
Inheritance
The IWDFMemory interface inherits from IWDFObject. IWDFMemory also has these types of members:

Methods
The IWDFMemory interface has these methods.
| IWDFMemory::CopyFromBuffer The CopyFromBuffer method safely copies data from the specified source buffer to a memory object. |
| IWDFMemory::CopyFromMemory The CopyFromMemory method safely copies data from the specified source buffer and prevents overruns that the copy operation might otherwise cause. |
| IWDFMemory::CopyToBuffer The CopyToBuffer method safely copies data from a memory object to the specified target buffer. |
| IWDFMemory::GetDataBuffer The GetDataBuffer method retrieves the data buffer that is associated with a memory object. |
| IWDFMemory::GetSize The GetSize method retrieves the size of the data buffer that is associated with a memory object. |
| IWDFMemory::SetBuffer The SetBuffer method assigns a specified buffer to a memory object that a driver created by calling IWDFDriver::CreatePreallocatedWdfMemory. |
