如何在本机Windows中模拟pthread条件变量？ [英] How emulate pthread condition variables in native Windows?
问题描述
我有一个使用Pthread进行线程处理的应用程序。主要是我使用
条件变量和相关函数调用：
- pthread_cond_wait（）
- pthread_cond_signal（）
- pthread_cond_broadcast（）
我的老板说我们因许可证问题（LGPL）而无法使用Pthread ..我们
只能使用Native Win32线程/互斥函数。
问题：有没有人有关于如何实现
条件变量与原生Win32函数的建议？
我在网上研究了这个，但我唯一能找到的东西（除了
PThread）就是函数PulseEvent ...但是MS文档说明了
功能不可靠，不应该使用。
提前感谢您的帮助，

My boss says we cant use Pthread because of licensing issues (LGPL) .. we
can only use Native Win32 threading/mutex functions.
Question: Does anyone out there have any suggestion on how to implement
Condition Variables with Native Win32 functions?
I researched this in the web, but the only thing I could find (besides
PThread) was the function PulseEvent ... but the MS documentation says that
function is not reliable and should not be used.
Thanks in advance for any help,

首先是免责声明：我对''nix'，'nux和''pux一无所知。
但是，如果你愿意的话购买一些帮助，你可以看看
Unix服务：
http://www.microsoft.com/technet/int...pthreads0.mspx
我认为它支持Posix线程。
此外，本机Windows支持互斥，信号量，事件和
关键部分（检查CreateMutex（），CreateSemaphore（），
CreateEvent（）和InitializeCriticalSection（））的文档。您应该能够使用少数这些同步来实现丢失的pthread调用
服务。
问候。

First the disclaimer: I know nothing of ''nix, ''nux and ''pux.
If however, you are willing to consider buying some help, you can look at
Services for Unix:
http://www.microsoft.com/technet/int...pthreads0.mspx
which I believe has support for Posix Threads.
In addition, native Windows has support for mutexes, semaphores, events and
critical sections ( check the docs for CreateMutex(), CreateSemaphore(),
CreateEvent() and InitializeCriticalSection() ). You should be able
implement the missing pthread calls with a handful of these synchronization
services.
Regards.

感谢您的建议。
我试过SFU几个月前和我有两个问题：（1）即时通讯使用
标准的Vis C ++，我认为它需要我买更贵的
版本; （2）它是_huge_。
我正在寻找一个围绕原生Windows线程的小包装器
模拟pthread条件变量的库函数。
我已经读过Pthread（对于Windows）的源代码，它相当精致
....我希望有人有创建了一个精简的简单包装器，
可以调节变量。

Thanks for the suggestions.
I tried SFU a few months ago and I had two problems with it: (1) im using
Standard Vis C++, and I think it required me to buy the more expensive
edition; and (2) it was _huge_.
I''m looking for just a little wrapper around the native Windows thread
library that emulates the pthread Condition Variable functions.
I''ve read the Pthread (for Windows) source code, and it is rather elaborate
.... I was hoping someone has created a stripped-down, simple wrapper that
does condition variables.
