Boost.Context 是一个提供单线程合作式多任务处理的基础库，通过封装当前线程的执行状态，包括栈、寄存器、CPU标志和指令指针等，实现特定的应用执行路径上的上下文实例。它适用于构建高阶抽象，如协程、用户级线程或类 C# yield 关键字的等价物。本文深入探讨 Boost.Context 在现代编程中的应用与优势。

New Libraries: Context

Boost.Context is a foundational library that provides a sort of cooperative multitasking on a single thread. By providing an abstraction of the current execution state in the current thread, including the stack (with local variables) and stack pointer, all registers and CPU flags, and the instruction pointer, afcontext_t instance represents a specific point in the application's execution path. This is useful for building higher-level abstractions, like coroutines,cooperative threads (userland threads) or an aquivalent to C# keyword yield in C++.
