For portability, I use boost::interprocess::file_lock::try_lock() upon some existing common file. (if it fails, program is already running so you can either exit or send to the other process program arguments or so...) Some parts of boost libraries are nice, some are ugly and bloated as hell... Interprocess is OK(ish). R.
