68 * Set: When any message is written to the screen.

69 * msg_nowait No extra delay for the last drawn message.

3869 * s, c, d, u, o, x, X, p (and synonyms: i, D, U, O - see below)
|
|
3870 * with flags: '-', '+', ' ', '0' and '#'.

3871 * An asterisk is supported for field width as well as precision.

3873 * Length modifiers 'h' (short int) and 'l' (long int) are supported.
|
|
3874 * 'll' (long long int) is not supported.
|
|
3875 *
|

3876 * The locale is not used, the string is used as a byte string. This is only
