[Boost-users] [Interprocess] Custom naming for the managed_external_buffer

Hello, I'm using a mapped file in order to share my objects between many processes and I already have my own kind of key to identify them. So instead of linking them to a in the function construct(), I would like to use my own type (providing convenient functions such as less(), operator==, ...) So I mean, instead of : MyObject * my_object = mapped_file.construct<MyObject>("object_name"); I want to known if there is a way to write something like : MyKey *object_key*(...) MyObject * my_object = mapped_file.construct<MyObject>(*object_key*); I'm taking a look at the section "Building custom indexeshttp://www.boost.org/doc/libs/1_39_0/doc/html/interprocess/customizing_inter..." but I am not sure to be able to solve my problem with that. Could someone confirm? Best regards, Thomas 2009/6/29 David Larsson

Hi! I'm outputting the progress from an externally executed command line application using the windows API call OutputDebugString. This means that I need to convert all line breaking characters to flush commands to make sure the text is outputted when a new line is received rather than when some underlying structure finds it suitable to linebreak. I've created a sink that writes to OutputDebugString and it works great, however unless I manually insert lots of std::endl (or flushing some other way) I won't get any output until the buffer is full.

Is it possible to write an iostream filter that forces a flush on newlines or is this something I need to handle before feeding data into my stream?

/David
