It's actually 0 if equal, positive if greater, negative if less than. > The strcmp() and strncmp() functions return an integer greater than, equal to, or less than 0, according to whether the string s1 is greater than, equal to, or less than the string s2. The comparison is done using unsigned characters, so that ‘\200’ is greater than ‘\0’.
