 *  rest of the number. This flag is ignored if "-" flag is specified.
402
 *
403
 * WIDTH:@n
404
 *  - Specify minimal width of printed argument. If it is bigger, width is ignored.
405
 * If width is specified with a "*" character instead of number, width is taken from
406
 * parameter list. And integer parameter is expected before parameter for processed
407
 * conversion specification. If this value is negative its absolute value is taken
408
 * and the "-" flag is set.
409
 *
410
 * PRECISION:@n
411
 *  - Value precision. For numbers it specifies minimum valid numbers.
412
 * Smaller numbers are printed with leading zeroes. Bigger numbers are not affected.
413
 * Strings with more than precision characters are cut off.
414
 * Just as with width, an "*" can be used used instead of a number.
415
 * An integer value is then expected in parameters. When both width and precision
416
 * are specified using "*", the first parameter is used for width and the second one
417
 * for precision.

 *
419

 *  - c Print single character.

 *
433
 *  - s Print zero terminated string. If a NULL value is passed as value, "(NULL)" is printed instead.
434
 *
435
 *  - P, p  Print value of a pointer. Void * value is expected and it is printed in hexadecimal notation with prefix
436
 *  (as with \%#X or \%#x for 32bit or \%#X / \%#x for 64bit long pointers).
437
 *
438
 *  - b Print value as unsigned binary number. Prefix is not printed by default. (Nonstandard extension.)
