template< class CharT, class Traits, class BidirIt > std::basic_ostream<CharT,Traits>&     operator<<( std::basic_ostream<CharT,Traits>& os,                 const sub_match<BidirIt>& m );		(since C++11)

Writes the representation of the matched subsequence m to the output stream os.

Equivalent to os << m.str().

Parameters

os	-	output stream to write the representation to
m	-	a sub-match object to output

Return value

os.
