[Applies to KMDF and UMDF]
The WDF_MEMORY_DESCRIPTOR_INIT_BUFFER function initializes a WDF_MEMORY_DESCRIPTOR structure so that it describes a specified buffer.
Descriptor [out]A pointer to a WDF_MEMORY_DESCRIPTOR structure.
Buffer [in]A pointer to a memory buffer.
BufferLength [in]The size, in bytes, of the memory buffer that Buffer points to.
The WDF_MEMORY_DESCRIPTOR_INIT_BUFFER function zeros the specified WDF_MEMORY_DESCRIPTOR structure and sets the structure's Type member to WdfMemoryDescriptorTypeBuffer. Then it sets the structure's u.BufferType.Buffer and u.BufferType.Length members to the values that the Buffer and BufferLength parameters specify, respectively.
