[Boost-users] [boost::interprocess]trouble creating a vector in a shared memory segment

15 Jul 2008

      I'm having some trouble creating a vector in a shared memory segment 
(compilation errors)

The code:

int main(){
	//Allocator for the event list
	typedef boost::interprocess::allocator
	<int,managed_shared_memory::segment_manager> EventAllocator;

	//the in memory vector of events
	typedef boost::interprocess::vector<int, EventAllocator> EventList;

	//is it already created?
	EventList* pEventList = segment.find<EventList>(EVENTSEGMENT_NAME).first;

}

The error:
d:\boost_1_35_0\boost\preprocessor\iteration\detail\local.hpp(37): error 
C2036: 'EventList *' : unknown size

And the trace:

DataHandle.cpp(53) : warning C4101: 'ex' : unreferenced local variable
