<p>A <b>cx_string</b> is similar to a standard C string, except that it grows automatically as text is appended or inserted. The character data the string contains is '\0' terminated in order to guarantee full compatibility with string utility functions processing standard C strings. Together with the character data it also stores the length of the string. </p>
