<div dir="ltr">Ew, Java... How about Python? It's almost as effecient as C code, and has a decent built-in library for threads. C has very few threading libraries(assuming you want a multi-platform solution) that I know of. Off the top of my head, I can think of SDL's thread support, though that's hardly extensive. If you can stand to code in C++(the wild syntax deviations make me cringe, personally), there are plenty of threading libraries available. So many, in fact, that it might be hard to find the jeans that fit the best, so to speak.<div>

It's still relatively new, and I don't trust that all compilers are going to produce the same code for something like threads so early on, especially Microsoft's compilers.

I might feel better about it in a year or two, when I can be sure that releasing my code using C++'s built-in threads won't break something for a user/other dev who tries to build in another compiler.</div>

I'm guessing you are asking which is easier to develop thread safe<br>

For any hope of "easy" you'd have to switch to C++. Doing that,<br>
