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 GetDataBuffer method retrieves the data buffer that is associated with a memory object.
A pointer to a variable that receives information that describes the size of the data buffer.
This parameter is optional. The driver can pass NULL if the driver does not require the information.
