WDF_INTERRUPT_EXTENDED_POLICY_INIT function (wudfinterrupt.h)
[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.]

Remarks
The WDF_INTERRUPT_EXTENDED_POLICY_INIT function zeros the specified WDF_INTERRUPT_EXTENDED_POLICY structure and sets the structure's Size member. It also sets the structure's Policy member to WdfIrqPolicyMachineDefault and sets the structure's Priority member to WdfIrqPriorityUndefined.
