编程语言 并发的C++扩展技术规范 2

[中文适用范围]： 本文件在ISO/IEC 14882的基础上，描述了计算机程序在使用C++编程语言调用具有并发执行的算法时所需实现的接口要求。文档中所描述的算法可以在广泛的计算机架构上实现。该文档是以相对于基标准的一系列差异形式撰写的。 本文件中描述的一些功能可能在未来版本的C++中考虑标准化，但目前它们并不属于ISO/IEC 14882:2020的标准内容。本文件中的某些功能可能永远不会被标准化，而另一些功能则可能以完全不同的形式被标准化。 本文件的目标是在ISO/IEC 14882:2020算法库中建立广泛存在的并发实践。它为希望提供这些扩展的供应商提供了建议。 [外文原描述]： This document builds upon ISO/IEC 14882 by describing requirements for implementations of an interface that computer programs written in the C++ programming language could use to invoke algorithms with concurrent execution. The algorithms described by this document are realizable across a broad class of computer architectures. This document is written as a set of differences from the base standard. Some of the functionality described by this document might be considered for standardization in a future version of C++, but it is not currently part of ISO/IEC 14882:2020. Some of the functionality in this document might never be standardized, and other functionality might be standardized in a substantially different form. The goal of this document is to build widespread existing practice for concurrency in the ISO/IEC 14882:2020 algorithms library. It gives advice on extensions to those vendors who wish to provide them.
