OpenGL function to determine whether you are in a glBegin block or not ?

No.
Why would you need a function to tell you that? You, as the programmer, should *always* know whether you''re within a glBegin()/glEnd() block.

Because I will be moving from object to object- sometimes I want to ensure that the glBegin flag really is on.
... i don''t think you quite understand what glBegin and glEnd do... you glBegin, draw the object, glEnd, draw the next object.

OK.
What I will be doing is tranferring program control from function to function to function.
I would have liked a method to make sure glEnd had not been called prematurely.
Oh well, I guess I''ll implement it in my code.

Well you can call:
glBegin
again and if it returns GL_INVALID_OPERATION then you are in a glBegin...glEnd block.
Just a dirty trick.
