The ACX_DEVICEINIT_CONFIG structure provides configuration information to the class extension.

Members

This field is set by the ACX_DEVICE_CONFIG_INIT function.

`Flags`

Reserved.

`SynchronizationScope`

A WDF_SYNCHRONIZATION_SCOPE value specifying how the framework will synchronize execution of an object's event callback functions.

Internal only. Do not change the default value.

`ExecutionLevel`

A WDF_EXECUTION_LEVEL value specifying the maximum IRQL at which the framework will call the event callback functions that a driver has supplied for a framework object.

Internal only. Do not change the default value.

`Context`

Pointer to the context space for the class extension.

Remarks

Instances of this structure must be initialized by calling the ACX_DEVICEINIT_CONFIG_INIT function. A pointer to an ACX_DEVICEINIT_CONFIG structure is passed as a parameter to the AcxDeviceInitInitialize function.

ACX requirements

Minimum ACX version: 1.0
