## Name

glEnableVertexAttribArray — Enable or disable a generic vertex attribute array

## C Specification

`void glEnableVertexAttribArray(` | GLuint index`)`;

`void glDisableVertexAttribArray(` | GLuint index`)`;

## Parameters

`index`

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

## Description

`glEnableVertexAttribArray` enables the generic vertex attribute array specified by `index`. `glDisableVertexAttribArray` disables the generic vertex attribute array specified by `index`. By default, all client-side capabilities are disabled, including all generic vertex attribute arrays. If enabled, the values in the generic vertex attribute array will be accessed and used for rendering when calls are made to vertex array commands such as glDrawArrays, glDrawElements, glDrawRangeElements, glMultiDrawElements, or glMultiDrawArrays.

## Errors

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

## Associated Gets

glGet with argument `GL_MAX_VERTEX_ATTRIBS`

glGetVertexAttrib with arguments `index` and `GL_VERTEX_ATTRIB_ARRAY_ENABLED` ``

glGetVertexAttribPointerv with arguments `index` and `GL_VERTEX_ATTRIB_ARRAY_POINTER`
