# glGenVertexArrays

## Name

glGenVertexArrays — generate vertex array object names

## C Specification

`void glGenVertexArrays(` | GLsizei n,
| GLuint *arrays`)`;

## Parameters

`n`

  Specifies the number of vertex array object names to generate.

`arrays`

  Specifies an array in which the generated vertex array object names are stored.

## Description

`glGenVertexArrays` returns `n` vertex array object names in `arrays`. There is no guarantee that the names form a contiguous set of integers; however, it is guaranteed that none of the returned names was in use immediately before the call to `glGenVertexArrays`.

Vertex array object names returned by a call to `glGenVertexArrays` are not returned by subsequent calls, unless they are first deleted with glDeleteVertexArrays.

The names returned in `arrays` are marked as used, for the purposes of `glGenVertexArrays` only, but they acquire state and type only when they are first bound.

## Errors

`GL_INVALID_VALUE` is generated if `n` is negative.

## Associated Gets
