| (1) | ||

1) 构造迭代器，将私有的 streambuf_type* 成员设为
buffer 并将 failed() 位设为 false 。若 buffer 是空指针则行为未定义。2) 同 ostreambuf_iterator(stream.rdbuf()) 。
参数
| stream | - | 将关联其 rdbuf() 到此迭代器的输出流 |
| buffer | - | 此迭代器要访问的输出流缓冲 |
示例
运行此代码
#include <iostream> #include <fstream> #include <iterator> int main() { std::basic_filebuf<char> f; f.open("test.txt", std::ios::out); std::ostreambuf_iterator<char> out1(&f); std::ostreambuf_iterator<wchar_t> out2(std::wcout); *out1 = 'a'; *out2 = L'a'; }
