Re: [Boost-users] Boost::interprocess::string problems

I can't seem to get the hang of strings though. I've looked around online and can't seem to find an example of how this should be set up, and I can't get it to accept an allocator. The only way I can seem to typedef one is something like:

typedef boost::interprocess::string BoostString - or - typedef boost::interprocess::basic_string<char> BoostString;

Just as any container, interprocess basic_string needs an allocator, but it's the third argument (just like std::string, by the way) : template class basic_string; so defint it like this: using namespace boost::interprocess; typedef basic_string shm_string; As with vector, you will need to pass an allocator to the string cosntructor. See also string_test.cpp test in boost/libs/interprocess/test for an example of shared memory strings. Best, Ion
