GLuint texture
);

Remarks
If the texture parameter is currently the name of a texture, the glIsTexture function returns GL_TRUE. The glIsTexture function returns GL_FALSE if texture is zero. It also returns GL_FALSE if it is a non-zero value that is not currently the name of a texture, or if an error occurs.
You cannot include calls to glIsTexture in display lists.
Note
The glIsTexture function is only available in OpenGL version 1.1 or later.
