  • Article

[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 SetBuffer method assigns a specified buffer to a memory object that a driver created by calling IWDFDriver::CreatePreallocatedWdfMemory.

  [in] SIZE_T BufferSize
);

Parameters
