Is 0 a valid OpenGL texture ID?

glGenTextures(1, &textureid);

Assuming that the texture was created succesfully, could textureid be 0?

Solution

  • The manual page for glGenTextures() says see also glIsTexture(); the latter will (according to that) always return GL_FALSE for a texture name of 0. So, 0 can't be a valid texture name.
