NtGdiDdSetExclusiveMode function
[This function is subject to change with each operating system revision. Instead, use the DirectDraw and Microsoft Direct3DAPIs; these APIs insulate applications from such operating system changes, and hide many other difficulties involved in interacting directly with display drivers.]
Notifies the driver when a Microsoft DirectDraw application is switching to or from exclusive mode.
Syntax
DWORD APIENTRY NtGdiDdSetExclusiveMode(
_In_ HANDLE hDirectDraw,
_Inout_ PDD_SETEXCLUSIVEMODEDATA puSetExclusiveModeData
);
Parameters
-
hDirectDraw [in]

Return value
NtGdiDdSetExclusiveMode returns one of the following callback codes.
| Return code | Description |
|---|---|
|
The driver has performed the operation and returned a valid return code for that operation. If this code is DD_OK, DirectDraw or Direct3D proceeds with the function. Otherwise, DirectDraw or Direct3D returns the error code provided by the driver and aborts the function. |
|
The driver has no comment on the requested operation. If the driver is required to have implemented a particular callback, DirectDraw or Direct3D reports an error condition. Otherwise, DirectDraw or Direct3D handles the operation as if the driver callback had not been defined by executing the DirectDraw or Direct3D device-independent implementation. |
