| 10 | <em class="parameter"><code>sampler</code></em> must be zero or the name of a sampler object previously returned from a call to | |

| 14 | When a sampler object is bound to a texture unit, its state supersedes that of | |
| 15 | the texture object bound to that texture unit. If the sampler name zero is bound to | |
| 16 | a texture unit, the currently bound texture's sampler state becomes active. A single | |
| 17 | sampler object may be bound to multiple texture units simultaneously. | |
