istreambuf_iterator::equal

非成员函数

operator==operator!=

 

template< class CharT, class Traits > bool operator==( const istreambuf_iterator<CharT,Traits>& lhs,                  const istreambuf_iterator<CharT,Traits>& rhs );	(1)
template< class CharT, class Traits > bool operator!=( const istreambuf_iterator<CharT,Traits>& lhs,                  const istreambuf_iterator<CharT,Traits>& rhs );	(2)

检查 lhs 与 rhs 是否合法，或是否均为非法，无关乎它们所用的流缓冲区对象。

1) 等价于 lhs.equal(rhs) 。

2) 等价于 !lhs.equal(rhs) 。

参数

lhs, rhs

-

要比较的流缓冲区迭代器

返回值

1) lhs.equal(rhs) 的结果。

2) !lhs.equal(rhs) 的结果。

异常

（无）
