[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 WUDF_WORKITEM_CONFIG structure contains information that is associated with a work item.
SizeThe size, in bytes, of this structure.
OnWorkItemFuncThe address of an OnWorkItem callback function.
AutomaticSerializationA Boolean value that, if TRUE, indicates that the framework will synchronize execution of the OnWorkItem callback function with callback functions from other objects that are underneath the work-item object's parent object. If FALSE, the framework does not synchronize execution of the OnWorkItem callback function.
Your driver must initialize the WUDF_WORKITEM_CONFIG structure by calling WUDF_WORKITEM_CONFIG_INIT. Your driver can then pass the structure to the IWDFDevice3::CreateWorkItem method as an input parameter.
Setting the AutomaticSerialization member of WUDF_WORKITEM_CONFIG to TRUE has no effect if the driver did not enable automatic callback synchronization by calling IWDFDeviceInitialize::SetLockingConstraint.
