Defined in header`<iterator>`
template<class CharT,class Traits> bool operator==(conststd::istreambuf_iterator<CharT,Traits>& lhs, conststd::istreambuf_iterator<CharT,Traits>& rhs);	(1)
template<class CharT,class Traits> bool operator!=(conststd::istreambuf_iterator<CharT,Traits>& lhs, conststd::istreambuf_iterator<CharT,Traits>& rhs);	(2)	(until C++20)
friendbool operator==(const istreambuf_iterator& lhs, std::default_sentinel_t);	(3)	(since C++20)

Checks whether bothlhs andrhs are valid, or both are invalid, regardless of the stream buffer objects they use.

1) Equivalent tolhs.equal(rhs).

2) Equivalent to!lhs.equal(rhs).

3) Checks whetherlhs is invalid. Equivalent tolhs.equal(istreambuf_iterator{}).
This function is not visible to ordinaryunqualified orqualified lookup, and can only be found byargument-dependent lookup when std::istreambuf_iterator<CharT,Traits> is an associated class of the arguments.

The!= operator issynthesized fromoperator==.

(since C++20)

[edit]Parameters

lhs, rhs

stream buffer iterators to compare

[edit]Return value

1) The result oflhs.equal(rhs).

2) The result of!lhs.equal(rhs).

3) The result oflhs.equal(istreambuf_iterator{}).

[edit]Exceptions

May throw implementation-defined exceptions.
