Cross platform multithreading

Hi all,

I am working in an application in which I have to create multithreaded application.
I want to know that ,is it possible to make multithreaded application cross platform ?
Since I have saw that mainly OS API's are used for this.....
Is there any way for creating it ???

Thanks

Make your own.

Look at the available thread APIs across the platforms you need to support, and decide what's important to you.

Then your code has say
myThreadHandle myThreadCreate ( void (*entryPt)(void*), void *param );


You then have two implementation files, say
mythread_linux.c
mythread_win32.c
BOTH of which implement

Code:

---

myThreadHandle myThreadCreate ( void (*entryPt)(void*), void *param ) {
  // do stuff to create a thread
}

---

You then link with the implementation file of your chosen platform.

Then say, if you later on want to port to BSD as well, it's a simple matter of writing a single (and hopefully pretty trivial)
mythread_bsd.c
which re-implements your thread API on the new platform.

The other 99% of your code is blissfully unaware that anything has happened.

Thanks for reply.....
Is there any available library for this like third party library etc...

Thanks

Is _beginthread and the others not standard C, or is that for windows only?

Some, but they come with baggage

Maybe it's reasonably partitioned to only link the bits you need.

Try sourceforge as well.

The boost library reportedly has threading support. I've never used it though, so I'm not sure how comprehensive it is.

_beginthread() is windows specific (IIRC, it is actually Microsoft compiler/library specific, although a couple of other vendors support it grudgingly).

On the topic of frameworks with baggage, there is also The ACE framework. When I say baggage, I'm not exagerating: ACE is a framework for communication between processes/threads/systems and multithreading support is a small part of that.

You could also take a look at OpenMP. It has supports from different compilers (including Visual Studio since 2005 (but I don't know if the Express edition supports it) and GCC since version 4.2). It's totally platform independant and it's quite easy to use. I already used it a few times in some small projects and indeed, it works.

boost::thread is fairly comprehensive with little to no baggage.
boost has other libraries that can help in a cross-platform project.
