BlitzMax Forums/OpenGL Module/OpenGL Quadrics pointer ???

This is the inaugural question on the new OpenGL forum (woohoo) hopefully it is not too obscure or confusing :)

I am having some trouble with OpenGL type conversions (maybe?)

it seems that glunewquadric returns an integer:

quadric = gluNewQuadric()

yet the quadric needs a byte pointer.

gluSphere(Qudric Ptr,radius,stacks,slices)

Global quadratic:Int Ptr	' Storage For Our Quadratic Objects

quadratic=Int Ptr gluNewQuadric()	' Create A Pointer To The Quadric Object (Return 0 If No Memory)
gluQuadricNormals(quadratic, GLU_SMOOTH)	' Create Smooth Normals
gluQuadricTexture(quadratic, GL_TRUE)		' Create Texture Coords

gluSphere(Int Ptr quadratic,1.3,32,32)	' Draw A Sphere With A Radius Of 1.3 And 32 Longitude And 32 Latitude Segments

And i correct something, no need "int ptr" in gluSphere function because quadratic is a pointer. :)
