SetBlendState routine

The SetBlendState function sets a blend state.

Syntax


PFND3D10DDI_SETBLENDSTATE SetBlendState;

VOID APIENTRY SetBlendState(
  _In_  D3D10DDI_HDEVICE hDevice,
  _In_  D3D10DDI_HBLENDSTATE hState,
  _In_  const FLOAT pBlendFactor,
  _In_  UINT SampleMask
)
{ ... }

Parameters

hDevice [in]

A handle to the display device (graphics context).

hState [in]

A handle to the blend state to set.

pBlendFactor [in]

A four-element array of single-precision float vectors that the driver uses to set the blend state.

SampleMask [in]

A sample format mask.

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 Microsoft 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 SetBlendState (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.
