printf(3S) printf(3S)
• an optional hh specifying that a following
n conversion specifier applies to a pointer to a
signed char argument
• an optional

j specifying that a following
n conversion specifier applies to a pointer to an
intmax_t argument
• an optional
l (the letter "ell"), specifying that a following
d, i, o, u,
x,orX conversion
character applies to a long integer arg
• an optional
l specifying that a following
n conversion character applies to a pointer to a
long integer arg
• an optional
L specifying that a following
a, A, e, E, f, F, g,orG
conversion character
applies to a long double
• an optional
ll specifying that a following
d, i, o, u, x,orX conversion character applies
to a long long integer arg
• an optional
t specifying that a following d, i, o, u, x
or X conversion specifier applies to
a ptrdiff_t or the corresponding unsigned type argument
• an optional
t specifying that a following n conversion specifier applies to a pointer to a
ptrdiff_t argument
• an optional
z specifying that a following d, i, o, u, x
or X conversion specifier applies to
a size_t argument or the corresponding signed integer type argument
• an optional
z specifying that a following n conversion specifier applies to a pointer to a
size_t argument arg.
For Itanium(R)-based systems if the optional decimal floating point feature is installed and
enabled, the following optional character specifications are allowed:
• an optional
H specifying that a following f, F, e, E,
g, G, a,or A conversion specifier
applies to a
_Decimal32 argument.
• an optional
D specifying that a following f, F, e, E,
g, G, a,or A conversion specifier
applies to a
_Decimal64 argument.
• an optional
DD specifying that a following f, F, e, E,
g, G, a,or A conversion specifier
applies to a
_Decimal128 argument.
5. An
h, hh, j, l, L, ll, t
,orz before any other conversion character is ignored.
6. A conversion character that indicates the type of conversion to be applied.
A field width or precision can be indicated by an asterisk instead of a digit string. In this case, an integer
arg supplies the field width or precision. The arg that is actually converted is not fetched until the
conversion letter is seen, so the args specifying field width, or precision, or both must appear in that
order before the arg, if any, to be converted. A negative field width is taken as a
- flag followed by a
positive field width. A negative precision is taken as if the precision were omitted. Format strings con-
taining %n$ conversion specifications can also indicate a field width or precision by the sequence *n$.
The n indicates the position of an integer arg. With the *n$ sequence, the args specifying field width or
precision can appear before or after the arg to be converted.
The flag characters and their meanings are:
’ The integer portion of the result of a decimal conversion (%i, %d, %u, %f, %F, %g, or %G)
will be formatted with thousands’ grouping characters. Thousands’ grouping and the
separator character are determined by the "grouping" and "thousands_sep" fields of the
LC_NUMERIC category respectively. (See localedef (4)). For other conversions the
behavior is undefined. The nonmonetary grouping character is used.
- The resulting conversion is left-justified within the field.
+ The resulting signed conversion always begins with a sign (+ or -).
