Best operating system abstraction?

I'm looking for something to divert the standard operating system functionality in C / C ++: span / kill the thread, send / receive a message, start / stop a timer, maybe even memory management, although I can probably handle this myself with my own buffer pool.

I want to be able to develop and unit test on Linux / windows and then recompile c / C ++ code for various O / Ses targets (for embedded systems: eCos, FreeRTOS, VxWorks, etc.)

Something like "light" might be best, hopefully just a library, maybe even a collection of macros.

Have you looked over the Boost library ? It has threads, timers, memory management, and a signal library.



The library is not a small download, but most of the library components are header-only implementations (although OS paragraph libraries usually need to be linked) and you should only use what you need.

Why don't you directly name only POSIX functions (POSIX1 seems to be all your needs) and set the POSIX level higher than incompatible operating system (reads like Microsoft Windows)?

I keep a (long) list of the OS Abstraction Libraries . Hope it helps.

I think the incentive is worth a look; it can provide you with the os abstraction, but also compiler independence and much, much more. Of course this requires C ++. Other options: Posix.

On your list:
eCos, VxWorks, Linux: good posix support so you can use that. freertos: see link

Windows doesn't have good posix support out of the box (see wikipedia Posix ) If cygwin is ok for you, you can use it. If you have to mix with Visual Studio, a library like boost seems more interesting (you take your mind off of it)
