将endline插入字符串流 [英] Inserting endline into a stringstream

问题描述

我们知道，当在文件流中插入 \\\
时，系统的相应行结束序列将被写入文件（例如 \r\\\
Windows）。在 std :: stringstream 中插入一个结束行是否会导致系统适当的行结束序列被写入字符串？例如：

We know that when inserting \n in a file stream, the appropriate end-of-line sequence for the system will be written to the file (e.g. \r\n for Windows). Does inserting an endline in a std::stringstream result in the system-appropriate end-of-line sequence being written to the string? For example:

#include <sstream>

int main()
{
    std::ostringstream oss;
    oss << std::endl;
    std::string endlineSequence = oss.str();
    bool isWindows = enlineSequence == "\r\n";
    bool isOldMac  = endlineSequence == "\r";
    bool isUnix    = endlineSequence == "\n";
    // Will this work???
}

推荐答案

系统特定行尾仅与文本文件相关。只要流只在内存中，它只是'\\\
'。

The system specific line endings are only relevant for text files. As long as the stream is only in memory, it is just '\n'.
