EGL_KHR_image_base defines these two functions, and so does
EGL_KHR_image (which is bascically the union of EGL_KHR_image_base and
EGL_KHR_image_pixmap).
On OS X, GLhandleARB is void *, which is of different size than GLuint
on 64-bit. Because of this, the implementation of
glGetAttachedObjectsARB must be different from glGetAttachedShaders,
since the pointers/ints are packed the output memory.
From Mesa:
/* The "Interactions with APPLE_vertex_array_object" section of the
* GL_ARB_vertex_array_object spec says:
*
* "The first bind call, either BindVertexArray or
* BindVertexArrayAPPLE, determines the semantic of the object."
