GsSetShader routine

The GsSetShader function sets the geometry shader code so that all of the subsequent drawing operations use that code.

Syntax


PFND3D10DDI_SETSHADER GsSetShader;

VOID APIENTRY GsSetShader(
  _In_  D3D10DDI_HDEVICE hDevice,
  _In_  D3D10DDI_HSHADER hShader
)
{ ... }

Parameters

hDevice [in]

A handle to the display device (graphics context).

hShader [in]

A handle to the geometry shader code object.

Return value

None

The driver can use the pfnSetErrorCb callback function to set an error code. For more information about setting error codes, see the following Remarks section.

Remarks

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 will determine that the error is critical. Even if the device was removed, the driver is not required to return D3DDDIERR_DEVICEREMOVED; however, if device removal interfered with the operation of GsSetShader (which typically should not happen), the driver can return D3DDDIERR_DEVICEREMOVED.

Requirements

Version

Available in Windows Vista and later versions of the Windows operating systems.
