| 587 | For active uniforms that are arrays, the size is the number of active elements in the array;\r | |

| 603 | machine units, relative to the beginning of the uniform block in the buffer object data store. For uniforms\r | |

| 609 | <parameter>uniformIndices</parameter> is returned. The stride of a uniform associated with the default uniform\r | |
| 610 | block is -1. Note that this information only makes sense for uniforms that are arrays. For uniforms that are\r | |
| 611 | not arrays, but are declared in a named uniform block, an array stride of zero is returned.\r | |
