管理DXUT框架的函數(shù)
|
函數(shù) |
描述 |
|
DXUTResetFrameworkState |
將框架狀態(tài)重置為初始默認(rèn)狀態(tài)，之前設(shè)置的框架狀態(tài)改變將失效。 |
|
DXUTShutdown |
觸發(fā)程序終止和清空框架 |
|
DXUTGetExitCode |
獲取框架的退出代碼 |
DXUTResetFrameworkState
Resets DXUT state to its initial default state. All
previous DXUT state changes are lost.
VOID DXUTResetFrameworkState() ;
Parameters
None.
Return Values
No return value.
Remarks
This function does not normally need to be called. It
is useful for testing purposes because the application process does not have to
be restarted to reset DXUT back to its initial state.
DXUTShutdown
Triggers program termination and DXUT cleanup.
VOID DXUTShutdown(
int nExitCode
) ;
Parameters
- nExitCode
- [in] The exit code returned via the
DXUTGetExitCode function. The default value is 0
Return Values
No return value.
Remarks
It is not necessary for the application to call this
function, since the application lifespan is handled by DXUT. However, the
application can call this function to cleanly terminate the application process.
DXUTGetExitCode
Get DXUT exit
code.
INT DXUTGetExitCode() ;
Parameters
None.
Return Values
A DXUT exit
code, which will be one of the following possible values.
|
Value |
Description |
|
0 |
Successful execution. |
|
1 |
An
undetermined error occurred. |
|
2 |
No
Direct3D device could be found with the specified device settings. |
|
3 |
A media
file could not be found. |
|
4 |
The
Direct3D device has a non-zero reference count, meaning that some
objects were not released. |
|
5 |
An error
occurred when attempting to create an Direct3D device. |
|
6 |
An error
occurred when attempting to reset an Direct3D device. |
|
7 |
An error
occurred in the device creation callback function. |
|
8 |
An error
occurred in the device creation callback function. |
|
9 |
The
incorrect version of Direct3D or D3DX is installed. |
|
10 |
The last
device used upon exit was a REF device type. |
|
11 |
The
device was removed. |
Remarks
The return
value of this function is typically used in the application as the return code
of the application's WinMain function. Command-line tests can then be performed
on applications using this return code.
The following
is an example of command-line usage that uses DXUT exit code:
start /wait BasicHLSL.exe
echo %errorlevel%

DXUTGetD3DObject |
獲取一個(gè)指向IDirect3D9對象的指針 |
|
DXUTGetD3D9Device |
獲取一個(gè)指向代表當(dāng)前設(shè)備的IDirect3DDevice9接口指針 |
|
DXUTGetDeviceSettings |
獲取用來創(chuàng)建當(dāng)前設(shè)備的結(jié)構(gòu)體DXUTDeviceSettings |
|
DXUTGetPresentParameters |
獲取當(dāng)前設(shè)備的提交（presentation）參數(shù) |
|
DXUTGetD3D9BackBufferSurfaceDesc |
獲取一個(gè)指向當(dāng)前設(shè)備后臺緩沖區(qū)表面的D3DSURFACE_DESC結(jié)構(gòu)體的指針 |
|
DXUTGetD3D9DeviceCaps |
獲取一個(gè)指向當(dāng)前設(shè)備的D3DCAPS9結(jié)構(gòu)體的指針 |
DXUTGetD3DObject
Get a pointer to the IDirect3D9 object.
IDirect3D9 * DXUTGetD3DObject() ;
Parameters
None.
Return Values
Pointer to the IDirect3D9 object. NULL is returned if
no IDirect3D9 object has been created. See Remarks.
Remarks
This function exposes access to a global IDirect3D9
object. The reference count on this object interface is not incremented, so a
calling function should not release the IDirect3D9 interface pointer returned by
this function.
DXUTGetDeviceSettings
Get the DXUTDeviceSettings structure used to create the
current device.
DXUTDeviceSettings DXUTGetDeviceSettings() ;
Parameters
None.
Return Values
DXUTDeviceSettings structure used to
create the current device.
Remarks
This settings structure can describe either a Direct3D
9 device or a Direct3D 10 device as defined the structure's DXUTDeviceVersion
member.
If no device exists, then the
DXUTDeviceSettings structure is filled with zeros.
DXUTGetPresentParameters
Get the presentation parameters of the Direct3D 9
device.
D3DPRESENT_PARAMETERS DXUTGetPresentParameters() ;
Parameters
None.
Return Values
The presentation parameters of the Direct3D 9 device.
Remarks
If no Direct3D 9 device exists, then the
D3DPRESENT_PARAMETERS structure is filled with zeros.
DXUTGetD3D9BackBufferSurfaceDesc
Get a pointer to a D3DSURFACE_DESC surface description
of the current Direct3D 9 back buffer.
CONST D3DSURFACE_DESC * DXUTGetD3D9BackBufferSurfaceDesc() ;
Parameters
None.
Return Values
Pointer to a D3DSURFACE_DESC surface description of the
current Direct3D 9 back buffer.
Remarks
If no Direct3D 9 device exists, then the
D3DSURFACE_DESC structure is filled with zeros.
DXUTGetD3D9DeviceCaps
Get a pointer to the D3DCAPS9 capabilities of the
current device.
CONST D3DCAPS9 * DXUTGetD3D9DeviceCaps() ;
Parameters
None.
Return Values
Pointer to the D3DCAPS9 capabilities of the Direct3D 9
device.
Remarks
If no Direct3D 9 device exists, then the D3DCAPS9
structure is filled with zeros.
