glIsTexture: determine if a name corresponds to a texture

Function Definition

 GLboolean glIsTexture(GLuint texture​);
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.
