21The function `mg_strncasecmp()` is a helper function to compare two strings. The comparison is case insensitive and only a limited number of characters are compared. This limit is provided as third parameter in the function call. The return value is **0** if both strings are equal, less then zero if the first string is less than the second in a lexical comparison, and greater than zero if the first string is greater than the second.
