How to assign the output return of a stored procedure called using C++ OCCI library

Question

I have a stored procedure in Oracle DB, which has multiple input params and multiple-output params(int, int, char, sys ref cursor, sys ref cursor, sys ref cursor).

How do I assign this output to a variable in C++? I can assign the output variable of int like this:

int output_x = stmt->getInt(1)

How to do the same for cursor output param and print it on the screen?
