() returns an std::streamsize, which is the signed counterpart of std::size_t // it only returns a negative value in the constructors of std::strstreambuf, so we can // safely cast to size_t (taken from http://en.cppreference.com/w/cpp/io/streamsize) hf->process_bytes(b, (...
根据https://en.cppreference.com/w/cpp/string/basic_string/getline:从输入中提取字符并将它们附加到 str 直到发生以下情况之一(按列出的顺序检查) 输入的文件结束条件,在这种情况下,getline 设置 eofbit。 下一个可用的输入字符是 delim,由 Traits::eq(c, delim) 测试,在这种情况下,分隔符从输入中提取,但不...
