  UINT AlignedByteOffsetForArgs
);

Parameter

• pBufferForArgs
  Typ: ID3D11Buffer*

  A pointer to an ID3D11Buffer, which is a buffer containing the GPU generated primitives.

• AlignedByteOffsetForArgs
  Typ: UINT

  Offset in pBufferForArgs to the start of the GPU generated primitives.

Rückgabewert

Hinweise

When an application creates a buffer that is associated with the ID3D11Buffer interface that pBufferForArgs points to, the application must set the D3D11_RESOURCE_MISC_DRAWINDIRECT_ARGS flag in the MiscFlags member of the D3D11_BUFFER_DESC structure that describes the buffer. To create the buffer, the application calls the ID3D11Device::CreateBuffer method and in this call passes a pointer to D3D11_BUFFER_DESC in the pDesc parameter.
