void glGetDoublev( GLenum pname, ___byte_vector params ); (The egg should probably be updated to replace or alias ___blob to ___byte_vector...) Note: you will receive an incompatible type warning as Chicken will attempt to pass a char* (the blob) to a function expecting double* without a cast. In practice that should not cause a problem. You could instead use blob->f64vector/shared, in which case your example becomes: (let ((bv (make-blob (* 16 8)))) (glGetDoublev GL_MODELVIEW_MATRIX (blob->f64vector/shared bv)) bv) I am not sure if you can declare a foreign type transformation on GLdouble* to perform this conversion automatically (nor whether that would be a good idea). You could write wrappers to do this though. Once you get to that point, though, your original method starts to look more attractive... _______________________________________________ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
