Getting Vertex-List from a "gluSphere" command

Is there a possiblity getting all the vertices of a sphere by calling
gluSphere? I can see a lot of spheres on screen, but how to find/get’em in memory,
to operate with these vertices, like saving
in a file?
Please help me? I don’t know what to do!
Please prevent telling me i’ve to write my own “gluSphere” function for getting the coordinates!

Afraid not. You can quite easily generate your own sphere however (procedurally).
