data (C++17)

bool equal ( const istreambuf_iterator & it ) const ;

Checks whether both * this and it are valid, or both are invalid, regardless of the stream buffer objects they use.

Parameters

another stream buffer iterator to compare to

Return value

true if both * this and it are valid, or both are invalid, false otherwise.

Exceptions

May throw implementation-defined exceptions.

Defect reports

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

DR	Applied to	Behavior as published	Correct behavior
LWG 110	C++98	the signature was bool equal ( istreambuf_iterator & it )	const s added
LWG 1126	C++98	LWG issue 110 was not properly resolved, leaving the parameter type as `istreambuf_iterator&`	const added
