PFND3D10DDI_RESOURCEUNMAP callback function

Description

The ResourceUnmap function unmaps a subresource of a resource.

Parameters

unnamedParam1

hDevice [in]

A handle to the display device (graphics context).

unnamedParam2

hResource [in]

A handle to the resource to unmap.

unnamedParam3

Subresource [in]

An index that indicates the subresource to unmap.

Remarks

The driver can use the pfnSetErrorCb callback function to set an error code.

The driver can call pfnSetErrorCb to set the D3DDDIERR_DEVICEREMOVED error code; however, the driver is not required to set D3DDDIERR_DEVICEREMOVED if the device was removed. Calls to pfnSetErrorCb to set any other error code are critical.

Restrictions on input values

For Windows Display Driver Model (WDDM) 1.3 and later drivers, the Microsoft Direct3D runtime supplies a restricted set of input values used by this function. For a list of all restricted values, see Direct3D rendering performance improvements.
