Question

I made some test and I was able to create and remove boost::interprocess::shared_memory_object in a C++/CLI executable without problems. In a C++/CLI dll plugin I’m only able to create the boost::interprocess::shared_memory_object but the removal fails. I verified that the file exists at the time of removal – it is present in boost::interprocess folder in a subfolder named “20110606204418.125000”. The memory hasn’t been mapped by any other process. Any ideas what might be the cause? At the beginning I thought it may have something to do with the project being a dll and targeting CLR but honestly I don’t know.
EDIT: the removal code is called by a different thread than the creation code – is this disallowed?

Answer 1

During debugging I noticed that the file path that is to be removed inside boost::interprocess::shared_memory_object::remove is different from the file created by boost::interprocess::shared_memory_object constructor – the path to be removed points at the root of “boost_interprocess” folder while the actually created file is in the “boost_interprocess/20110606204418.125000” folder. So I reported a bug to boost. We will see what they do about it.
