regex_iterator::operator=

Compares iterators for equality.

bool operator==(const regex_iterator& right);

right

The iterator to compare to.

The member function returns true if *this and right are both end-of-sequence iterators or if neither is an end-of-sequence iterator and begin == right.begin, end == right.end, pregex == right.pregex, and flags == right.flags. Otherwise it returns false.
