The WDF_WORKITEM_CONFIG structure contains information that is associated with a work item.
SizeThe size, in bytes, of this WDF_WORKITEM_CONFIG structure.
EvtWorkItemFuncThe address of an EvtWorkItem event callback function.
AutomaticSerializationA Boolean value that, if TRUE, indicates that the framework will synchronize execution of the EvtWorkItem callback function with callback functions from other objects that are underneath the work-item object's parent object. For more information, see the following Remarks section. If FALSE, the framework does not synchronize execution of the EvtWorkItem callback function.
Your driver must initialize the WDF_WORKITEM_CONFIG structure by calling WDF_WORKITEM_CONFIG_INIT. Your driver can then pass the structure to the WdfWorkItemCreate method as an input parameter.
Setting the AutomaticSerialization member of WDF_WORKITEM_CONFIG to TRUE has no effect if the parent object's synchronization scope is set to WdfSynchronizationScopeNone.
If AutomaticSerialization is TRUE, the parent object's execution level must be WdfExecutionLevelPassive.
For more information about AutomaticSerialization and synchronizing driver callback functions, see Synchronization Techniques for Framework-Based Drivers.
