[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_INIT macro initializes a driver's WUDF_WORKITEM_CONFIG structure.

Syntax

void WUDF_WORKITEM_CONFIG_INIT(
  [out] PWUDF_WORKITEM_CONFIG pConfig,
  [in]  PFN_WUDF_WORKITEM     OnWorkItemFunc
);

Parameters

[out] pConfig

A pointer to the caller-allocated WUDF_WORKITEM_CONFIG structure to initialize.

[in] OnWorkItemFunc

The address of the driver's OnWorkItem event callback function.

Return value

None

Remarks

Drivers must call WUDF_WORKITEM_CONFIG_INIT before calling IWDFDevice3::CreateWorkItem.

The WUDF_WORKITEM_CONFIG_INIT function stores the pointer that the OnWorkItemFunc parameter specifies and sets the AutomaticSerialization member of the WUDF_WORKITEM_CONFIG structure that is pointed to by the pConfig parameter to TRUE.
