istreambuf_iterator::equal
Tests for equivalence between two input stream buffer iterators.
bool equal(
const istreambuf_iterator<CharType, Traits>& _Right
) const;
Parameters
- _Right
The iterator for which to check for equality.
Return Value
true if both istreambuf_iterators are end-of-stream iterators or if neither is an end-of-stream iterator; otherwise false.
Remarks
A range is defined by the istreambuf_iterator to the current position and the end-of-stream iterator, but since all non-end-of stream iterators are equivalent under the equal member function, it is not possible to define any subranges using istreambuf_iterators. The == and != operators have the same semantics.
Example
// istreambuf_iterator_equal.cpp
// compile with: /EHsc
#include <iterator>
#include <iostream>
int main( )
{
using namespace std;
cout << "(Try the example: 'Hello world!'\n"
<< " then an Enter key to insert into the output,\n"
<< " & use a ctrl-Z Enter key combination to exit): ";
istreambuf_iterator<char> charReadIn1 ( cin );
istreambuf_iterator<char> charReadIn2 ( cin );
bool b1 = charReadIn1.equal ( charReadIn2 );
if (b1)
cout << "The iterators are equal." << endl;
else
cout << "The iterators are not equal." << endl;
}
Hello world!
