glIsTexture 3G
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.

## Notes

`glIsTexture` is available only if the GL version is 1.1 or greater.

## Errors

`GL_INVALID_OPERATION` is generated if `glIsTexture` is executed between the execution of glBegin and the corresponding execution of glEnd.
