std::match_results<BidirIt,Alloc>::length: std::match_results<BidirIt,Alloc>::length
Command to display std::match_results<BidirIt,Alloc>::length manual in Linux: $ man 3 std::match_results<BidirIt,Alloc>::length
NAME
std::match_results<BidirIt,Alloc>::length - std::match_results<BidirIt,Alloc>::length
Synopsis
difference_type length( size_type n = 0 ) const; (since C++11)
Returns the length of the specified sub-match.
If n == 0, the length of the entire matched expression is returned.
If n > 0 && n < size(), the length of nth sub-match is returned.
if n >= size(), a length of the unmatched match is returned.
The call is equivalent to (*this)[n].length().
Parameters
n - integral number specifying which match to examine
Return value
The length of the specified match or sub-match.
See also
returns specified sub-match
operator[] (public member function)
returns the length of the match (if any)
length (public member function of std::sub_match<BidirIt>)
