'Declaration
Public Enumeration SetDataOptions

public enum SetDataOptions

	Member name	Description
	None	Portions of existing data in the buffer may be overwritten during this operation.
	Discard	The SetData operation will discard the entire buffer. A pointer to a new memory area is returned so that the direct memory access (DMA) and rendering from the previous area do not stall.
	NoOverwrite	The SetData operation will not overwrite existing data in the vertex and index buffers. Specifying this option allows the driver to return immediately from a SetData operation and continue rendering.
