Thanks,

I didn't realize that in the C++ program I used for example it is opssible 
to use a function without using the return part,

unit is compiling.

My program seems correct now, but I get the following error message:

opengl-glu.ads:373:31: warning: subprogram pointer 
"gluNurbsCallback.CallBackFunc" should have foreign convention
opengl-glu.ads:373:31: warning: add Convention pragma to declaration of 
"GLU.GLUFUNCPTR" at line 231

This is found in a standard unit nl. the adabindings to Open GL, GLU and 
GLUT

Can I disregard this warning or should I do something to avoid it. I don't 
thoink I should be altering my copy of the ADA bindings so
where should I do something.
In my program I don't call this routine directly soit is a result of a call 
from another routine within the ADA bindings.
