std::basic_filebuf::uflow

性病：基本[医]filebuf：：uflow

protected: virtual int_type uflow()​​

行为类似于underflow()，但如果underflow()%28不返回Traits::eof()%29，然后为GET区域前进下一个指针。换句话说，使用由underflow()...

参数

%280%29

返回值

在成功的情况下被读取和消耗的字符的价值，或Traits::eof()万一失败。

例

另见

uflow virtualreads characters from the associated input sequence to the get area and advances the next pointer (virtual protected member function of std::basic_streambuf)
underflow virtualreads from the associated file (virtual protected member function)
overflow virtualwrites characters to the associated file from the put area (virtual protected member function)
