## Parameters

`index`

- Specifies the index of the generic vertex attribute to be enabled or disabled.

## Description

glDrawArraysInstanced

,

glDrawElements

,

glDrawElementsInstanced

, or

glDrawRangeElements

.

## Errors

`GL_INVALID_VALUE` is generated if `index` is greater than or equal to `GL_MAX_VERTEX_ATTRIBS`.
