本文介绍了如何使用 Boost 制作关键部分?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 29岁程序员,3月因学历无情被辞! 对于我的跨平台应用程序,我已经开始使用 Boost,但我无法理解如何实现代码来重现 Win32 的关键部分或 .Net 的 lock 的行为.For my cross-platform application I have started to use Boost, but I can't understand how I can implement code to reproduce behavior of Win32's critical section or .Net's lock.我想写一个方法Foo,可以从不同的线程调用来控制对共享字段的写操作.应该允许同一线程内的递归调用(Foo() -> Foo()).I want to write a method Foo that can be called from different threads to control write operations to shared fields. Recursive calls within the same thread should be allowed (Foo() -> Foo()).在 C# 中这个实现非常简单:In C# this implementation is very simple:object _synch = new object();void Foo(){ lock (_synch) // one thread can't be lock by him self, but another threads must wait untill { // do some works if (...) { Foo(); } }}推荐答案通过 boost 你可以使用 boost::lock_guard class:With boost you can use boost::lock_guard<> class:class test{public: void testMethod() { // this section is not locked { boost::lock_guard<boost::recursive_mutex> lock(m_guard); // this section is locked } // this section is not locked }private: boost::recursive_mutex m_guard;};PS 这些类位于 Boost.Thread 库中.PS These classes located in Boost.Thread library. 这篇关于如何使用 Boost 制作关键部分?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云! 07-25 07:49
