Hi,
I need to store in the shared memory structure for Quadtree.
It is a class with 4 pointers for tree regions and vector of points:
class CNode4
{
...
CNode4* node0;
CNode4* node1;
CNode4* node2;
CNode4* node3;
vector<vec2> pointArray;
};
I have tried with
class CNode4
{
...
offset_ptr<CSNode4> node0;
...
};
and using as:
typedef allocator
void_allocator;
const void_allocator alloc_void(segment.get_segment_manager());
CSNode4* rootNode = segment.construct<CSNode4> (_RootNode) (alloc_void);
rootNode->node0 = new CSNode4(alloc_void,...);
this works until I try to static_cast node0
offset_ptr<CSNode4> N1 = static_cast(rootNode->node0);
I get:
(MSVC 2010, boost 1.42)
error C2440: 'static_cast' : cannot convert from
'boost::interprocess::offset_ptr<PointedType>' to 'CSNode4 *'
what am I doing wrong?
Thanks,
Ivan
