Subject: convert a C/C++ array to a Ruby array

Hello! 
 
While writting a Ruby extension, consider the prototype: 
 
double * foo(void); 
 
I would like, optimally, to return a Ruby array with floats, but the problem is that I don't know 
the length of the C array of doubles which foo() returns. 
 
Is there a way to accomplish such a thing? If not, how should the Right (TM) Ruby  
extension treat such a prototype? 
 
I am compiling with g++, so I can use all the functionality C++ provides. 
 
Regards, 
Elias
