CGMP refers to the Current Good Manufacturing Practice regulations enforced by the FDA. CGMPs provide for systems that assure proper design, monitoring, and control of manufacturing processes and facilities. Adherence to the CGMP regulations assures the identity, strength, quality, and purity of drug ...
无锁编程主要依靠原子操作(Atomic Operations)来实现。原子操作是一种不可分割的操作,保证在执行过程中不会被其他线程中断。在C++中,这通常通过 std::atomic 类型和相关函数实现,它们可以对基本数据类型进行无锁操作。 2.1.3 优势与应用场景 性能提升:由于减少了线程阻塞和上下文切换,无锁编程可以显著提高程序的性能,...
The default behavior of all atomic operations in the library provides for sequentially consistent ordering (see discussion below). That default can hurt performance, but the library's atomic operations can be given an additional std::memory_order argument to specify the exact constraints, beyond atom...
对于第4个printf,首先执行++i,返回i,此时i为8,再执行i++,返回值是8,此时i为9,依次将i,8也就是9,8压入栈中,得到输出结果。 上面的分析也是基于VS搞的,不过准确来说函数多个参数的计算顺序是未定义的(the order of evaluation of function arguments are undefined)。笔试题目的运行结果随不同的编译器而异。

因为它只对你的操作系统有要求,比如 Windows 上编译的动态库是 .dll 文件,Linux 上编译的动态库是 .so 文件,只要操作系统一致,那么任何提供了 ctypes 模块的 Python 解释器都可以调用。这种方式的使用场景是 Python 和 C / C++ 不需要做太多的交互,比如嵌入式设备,可能只是简单调用底层驱动提供的某个接口而已。
