DXGKCB_HARDWARECONTENTPROTECTIONTEARDOWN callback function (d3dkmddi.h)
DXGKCB_HARDWARECONTENTPROTECTIONTEARDOWN is called when a hardware content protection tear-down event occurs.
Syntax
DXGKCB_HARDWARECONTENTPROTECTIONTEARDOWN DxgkcbHardwarecontentprotectionteardown;
void DxgkcbHardwarecontentprotectionteardown(
[in] IN_CONST_HANDLE hAdapter,
[in] UINT Flags
)
{...}
Parameters
[in] hAdapter
A handle to the graphics adapter where the tear-down event is occurring.
[in] Flags
Additional flags defined by the DXGK_HARDWARE_CONTENT_PROTECTION_TEARDOWN_FLAGS enumeration.
Return value

Remarks
The kernel-mode display miniport driver should always call DXGKCB_HARDWARECONTENTPROTECTIONTEARDOWN both before and after a hardware content protection tear-down event occurs.
DXGKCB_XXX functions are implemented by Dxgkrnl. To use this callback function, call DxgkCbHardwareContentProtectionTeardown via the DXGKRNL_INTERFACE. The driver can call this callback at either passive level or at dispatch level.
