glGenTextures - OpenGL 4 Reference Pages

## Name

glGenTextures — generate texture names

## C Specification

`void glGenTextures(` | GLsizei n,
| GLuint * textures`)`;

## Parameters

`n`

  Specifies the number of texture names to be generated.

`textures`

  Specifies an array in which the generated texture names are stored.

## Description

`glGenTextures` returns `n` texture names in `textures`. 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 `glGenTextures`.

The generated textures have no dimensionality; they assume the dimensionality of the texture target to which they are first bound (see glBindTexture).

Texture names returned by a call to `glGenTextures` are not returned by subsequent calls, unless they are first deleted with glDeleteTextures.

## Errors

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

## Associated Gets
