Provides a direct access to the string buffer. Returns a pointer for directly accessing the string buffer. This pointer valid remains valid as long as the string is not modified by other means. Positive values for argument n# represent the length of the returned buffer. The returned string buffer will be large enough to hold at least n# characters plus a null character. If n# is positive but smaller than the string length, the string will be truncated to n# characters.
