NAME

std::char_traits::compare,std::char_traits::compare, - std::char_traits::compare,std::char_traits::compare,

Synopsis


std::char_traits<char32_t>::compare


static int compare( const char_type* s1, const char_type*
s2, (constexpr since C++17)
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.


See CharTraits for the general requirements on character traits for X::compare.

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.

Complexity


Linear in count.
