C: Multithreading
提问by madtapper
Is multithreading supported in C? If yes, then how do I try? Is there any open source library that lets me do it and is the library supported on Mac OS X?
C 支持多线程吗？如果是，那么我该如何尝试？是否有任何开源库可以让我这样做，Mac OS X 是否支持该库？
I haven't found any article saying that it's supported.
我还没有找到任何文章说它受支持。

C is not intrinsically a multithreaded language; however there are many libraries which add threading functionality.
C 本质上不是多线程语言；然而，有许多库添加了线程功能。
pthreadsis a library compatible with any POSIX system, so it is supported on OSX. I found https://computing.llnl.gov/tutorials/pthreads/to be a good place to start.Win32 has a threading library for C described at http://msdn.microsoft.com/en-us/library/y6h8hye8(v=vs.80).aspx.
Glibadds threading supported, and has the advantage of being completely cross-platform, as long as glib is installed on the target machine. There is some information here: http://developer.gnome.org/glib/2.28/glib-Threads.html
pthreads是一个与任何 POSIX 系统兼容的库，因此它在 OSX 上受支持。我发现https://computing.llnl.gov/tutorials/pthreads/是一个很好的起点。Win32 有一个 C 线程库，在http://msdn.microsoft.com/en-us/library/y6h8hye8(v=vs.80).aspx 中有描述。
Glib增加了线程支持，并且具有完全跨平台的优点，只要目标机器上安装了glib。这里有一些信息：http: //developer.gnome.org/glib/2.28/glib-Threads.html

the new dialect - C1X, will offer multi-threading out of the box, as stated from wikipedia:
正如维基百科所述，新方言 - C1X 将提供开箱即用的多线程：
Multithreading support (_Thread_local storage-class specifier, header including thread creation/management functions, mutex, condition variable and thread-specific storage functionality, as well as the _Atomic type qualifier and for uninterruptible object access).
多线程支持（_Thread_local 存储类说明符，标头包括线程创建/管理函数、互斥锁、条件变量和线程特定的存储功能，以及 _Atomic 类型限定符和用于不间断对象访问）。
currently of courae as mentioned above, multi-threading is not supported in the newest dialect of c - C99
目前如上所述，c - C99 的最新方言不支持多线程

C has no concept whatever of threads. There is no thread support in C Standard. There are extensions available that can implement multi threading - one of which is pthreads.
C 没有任何线程的概念。C 标准中没有线程支持。有一些扩展可以实现多线程——其中之一是 pthreads。
Be aware because C language has no natural support of threads you as the programmer have to take care of everything and you will not be protected against any of the pitfalls of multi-threaded programming.
请注意，因为 C 语言没有对线程的自然支持，您作为程序员必须照顾一切，并且您不会受到多线程编程的任何陷阱的保护。

I would guess that the majority of multithreaded programming on Mac OS X is done in Objective-C or C++, not plain C. (I realize that this isn't exactly an answer to the question that you asked, but you might want to know about alternatives.) In Objective-C, you'd use NSThread or, in Snow Leopard and later, Grand Central Dispatch (GCD). In C++, you could use the threads library from boost.org, which has the advantage of being cross-platform.
我猜想 Mac OS X 上的大部分多线程编程都是用 Objective-C 或 C++ 完成的，而不是普通的 C。关于替代方案。）在 Objective-C 中，您将使用 NSThread，或者在 Snow Leopard 和更高版本中使用 Grand Central Dispatch (GCD)。在 C++ 中，您可以使用 boost.org 中的线程库，它具有跨平台的优点。

Pthreads. OSX has posix support.
线程。OSX 有 posix 支持。
