std::basic_ifstream::close

性病：基本[医]如果流：：关闭

void close(​​

关闭关联文件。

有效呼叫rdbuf()->close()如果操作过程中发生错误，setstate(failbit)叫做。

参数

%280%29

返回值

%280%29

注记

此函数由Basic的析构函数调用。[医]如果流对象超出作用域，通常不会直接调用。

例

另见

is_openchecks if the stream has an associated file (public member function)
openopens a file and associates it with the stream (public member function)
closeflushes the put area buffer and closes the associated file (public member function of std::basic_filebuf)
