glIsTexture - OpenGL 4 Reference Pages

## Name

glIsTexture — determine if a name corresponds to a texture

## C Specification

`GLboolean glIsTexture(` | GLuint texture`)`;

## Parameters

`texture`

  Specifies a value that may be the name of a texture.

## Description

`glIsTexture` returns `GL_TRUE` if `texture` is currently the name of a texture. If `texture` is zero, or is a non-zero value that is not currently the name of a texture, or if an error occurs, `glIsTexture` returns `GL_FALSE`.

A name returned by glGenTextures, but not yet associated with a texture by calling glBindTexture, is not the name of a texture.
