2.13. Mantaining references to Quirrel values from the C API

Quirrel allows to reference values through the C API; the function sq_getstackobj() gets a handle to a quirrel object(any type). The object handle can be used to control the lifetime of an object by adding or removing references to it( see sq_addref() and sq_release()). The object can be also re-pushed in the VM stack using sq_pushobject().:

HSQOBJECT obj;

sq_resetobject(&obj); //initialize the handle
sq_getstackobj(v,-2,&obj); //retrieve an object handle from the pos -2
sq_addref(v,&obj); //adds a reference to the object

... //do stuff

sq_pushobject(v,obj); //push the object in the stack
sq_release(v,&obj); //relese the object
