+.Ft int
+.Fn strncmp "const char *s1" "const char *s2" "size_t len"
+.Sh DESCRIPTION
+The
+.Fn strcmp
+and
+.Fn strncmp
+functions lexicographically compare the NUL-terminated strings
+.Fa s1

+to whether the string
+.Fa s1
+is greater than, equal to, or less than the string
+.Fa s2 .
+The comparison is done using unsigned characters, so that
+.Ql \e200
+is greater than
+.Ql \e0 .
