std::basic_osyncstream是一个模板类,它依赖于底层流类型(如std::ostream或std::wostream)。要使用std::basic_osyncstream,首先需要包含头文件<syncstream>,然后创建一个std::basic_osyncstream对象,并将其绑定到一个底层流对象上。以下是一个简单的示例: 代码语言:cpp 代码运行次数:0 运行 AI代

它提供保证:所有对最终目标缓冲(上例中为 std::cout )作出的输出将免除数据竞争,而且将不以任何方式穿插或截断,只要每次对该最终目标缓冲的写入都通过 std::basic_osyncstream (可以不同的)实例进行。 std::basic_osyncstream 的典型实现仅保有一个数据成员:被包装的 std::basic_syncbuf。
#include <syncstream> #include <iostream> int main() { { std::osyncstream bout(std::cout); std::bout << "Hello," << '\n'; // 不冲入 std::bout.emit(); // 传输字符; cout 不冲入 std::bout << "World!" << std::endl; // 提醒冲入; cout 不冲入 std::bout.emit(); /...

I want to define a byte stream with C++。Therefore I used basic_ifstream<unsigned char> as the container。 It works good in Visual Studio 'byte' means 'unsigned char' However, when I migrate the code to Android Studio, it outputs the following error: ...
