std::sub_match::compare(3)     C++ Standard Libary    std::sub_match::compare(3)

NAME
     std::sub_match::compare - std::sub_match::compare

Synopsis
	int compare( const sub_match& m ) const;   (1) (since C++11)
	int compare( const string_type& s ) const; (2) (since C++11)
	int compare( const value_type* c ) const;  (3) (since C++11)

	1) Compares two sub_match directly by comparing their underlying charac-
     ter
	sequences. Equivalent to str().compare(m.str()).
	2)   Compares  a  sub_match  with  a  std::basic_string.  Equivalent  to
     str().compare(s).
	3) Compares a sub_match with a null-terminated sequence of the	underly-
     ing character
	type pointed to by s. Equivalent to str().compare(c).

	This  function	is  infrequently  used directly by application code. In-
     stead, one of the
	non-member comparison operators is used.

Parameters
	m - a reference to another sub_match
	s - a reference to a string to compare to
	c - a pointer to a null-terminated character sequence of the  underlying
     value_type
	    to compare to

Return value
	A  value less than zero if this sub_match is less than the other charac-
     ter sequence,
	zero if the both underlying character sequences are equal, greater  than
     zero if this
	sub_match is greater than the other character sequence.
