Error in documentaiton "Using smart pointers with Boost.Intrusive containers"

Reported by: DeepThought <deeptho@…> Owned by: igaztanaga
Milestone: To Be Determined Component: interprocess
Version: Boost 1.45.0 Severity: Problem
Keywords: Cc:


The example at is erroneous and misleading.

First of all, some declarations about namespaces are missing.

More importantly, the following line

typedef ip::list<shared_memory_data> shm_list_t;

defines shm_list_t in such a way that it uses standard allocators. This means that the list items are created in normal memory, which is not what the example intends.

Even worse, the "Check all the inserted nodes" test fails to detect this problem.

The example is problematic anyway, because it only deals with one process.

The attachment could serve as a starting point for a good and working example. I suspect you won't like the printf's in it....

The intention was not to show a full example, just to point that intrusive accepts custom smart pointers. I've fixed the list definition to be an intrusive list in Boost 1.47
