PFND3D11DDI_DESTROYCOMMANDLIST callback function (d3d10umddi.h)
The DestroyCommandList function destroys a command list.
Syntax
PFND3D11DDI_DESTROYCOMMANDLIST Pfnd3d11ddiDestroycommandlist;
void Pfnd3d11ddiDestroycommandlist(
D3D10DDI_HDEVICE unnamedParam1,
D3D11DDI_HCOMMANDLIST unnamedParam2
)
{...}
Parameters
unnamedParam1
hDevice [in]
A handle to the display device (graphics context).
unnamedParam2
hCommandList [in]
A handle to the driver's private data for the command list to destroy. The Microsoft Direct3D runtime frees the memory region that it previously allocated for the command list. Therefore, the driver can no longer access this memory region.
Return value
None
Remarks
The driver can use the pfnSetErrorCb callback function to set an error code.
The driver is only required to implement DestroyCommandList if the driver supports the D3D11DDICAPS_COMMANDLISTS_BUILD_2 capability that can be returned in the D3D11DDI_THREADING_CAPS structure from a call to the GetCaps(D3D10_2) function.
The driver should not encounter any error, except for D3DDDIERR_DEVICEREMOVED. Therefore, if the driver passes any error, except for D3DDDIERR_DEVICEREMOVED, in a call to the pfnSetErrorCb function, the Direct3D runtime determines that the error is critical. Even if the device is removed, the driver is not required to return D3DDDIERR_DEVICEREMOVED; however, if device removal interferes with the operation of DestroyCommandList (which typically should not happen), the driver can return D3DDDIERR_DEVICEREMOVED.
The driver can implement a DestroyCommandList function that contains a switch statement to process the destruction of command lists and the lightweight destruction of command lists. That is, the driver can implement one DestroyCommandList, and can set the pfnRecycleDestroyCommandList member of the D3D11DDI_DEVICEFUNCS structure to point to DestroyCommandList along with the pfnRecycleDestroyCommandList member of D3D11DDI_DEVICEFUNCS to point to DestroyCommandList. However, to improve performance, the driver can implement separate DestroyCommandList and RecycleDestroyCommandList functions.
