/** Print formatted string.
 *
 * Print string formatted according to the @fmt parameter
 * and variadic arguments. Each formatting directive
 * must have the following form:
 * % [ flags ] [ width ] [ .precision ] [ type ] conversion
 *
 * FLAGS:
 * #    Force to print prefix.
 *  For conversion %o the prefix is 0, for %x and %X prefixes are 0x and 0X and for conversion %b the prefix is 0b.
 * -    Align to left.
 * +    Print positive sign just as negative.
 *   (space)    If the printed number is positive and '+' flag is not set, print space in place of sign.
 * 0    Print 0 as padding instead of spaces. Zeroes are placed between sign and the rest of the number.
 *  This flag is ignored if '-' flag is specified.
 *
 * WIDTH:
 * Specify minimal width of printed argument. If it is bigger, width is ignored.
 * If width is specified with a '*' character instead of number, width is taken from parameter list.
 * And integer parameter is expected before parameter for processed conversion specification.
 * If this value is negative its absolute value is taken and the '-' flag is set.
 *
 * PRECISION:
 * Value precision. For numbers it specifies minimum valid numbers.
 * Smaller numbers are printed with leading zeroes. Bigger numbers are not affected.

 * z    __native (non-standard extension)
 *
 *
 * CONVERSIONS:
 *
 * %    Print percentage character itself.
 *
 * c    Print single character.
 *
 * s    Print zero terminated string. If a NULL value is passed as value, "(NULL)" is printed instead.
 *
 * P, p Print value of a pointer. Void * value is expected and it is printed in hexadecimal notation with prefix
 * (as with %#X or %#x for 32bit or %#X / %#x for 64bit long pointers).
 *
 * b    Print value as unsigned binary number. Prefix is not printed by default. (Nonstandard extension.)
 *
 * o    Print value as unsigned octal number. Prefix is not printed by default.
 *
 * d,i  Print signed decimal number. There is no difference between d and i conversion.
 *
 * u    Print unsigned decimal number.
 *
 * X, x Print hexadecimal number with upper- or lower-case. Prefix is not printed by default.
 *
 * All other characters from @fmt except the formatting directives
 * are printed in verbatim.
 *
 * @param fmt Formatting NULL terminated string.
 * @return Number of printed characters or negative value on failure.
