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

NAME
       std::char_traits::compare - std::char_traits::compare

Synopsis
	  static  int  compare(	 const	char_type*  s1,	 const	char_type* s2,
       (until C++17)
	  std::size_t count );
	  static constexpr int compare(	const char_type* s1, const  char_type*
       (since C++17)
	  s2, std::size_t count	);

	  Compares  the	first count characters of the character	strings	s1 and
       s2. The
	  comparison is	done lexicographically.

	  If count is zero, strings are	considered equal.

Parameters
	  s1, s2 - pointers to character strings to compare
	  count	 - the number of characters to	compare	 from  each  character
       string

Return value
	  Negative value if s1 is less than s2.

	  0 if s1 is equal to s2.

	  Positive value if s1 is greater than s2.

Exceptions
	  Throws nothing.

Complexity
	  Linear in count.
