fprintf
5. An optional l, h, or L indicating that the argument is of an alternate type. When used
in conjunction with an integer conversion character, an l or h indicates a long or short
integer argument, respectively. When used in conjunction with a floating-point
conversion character, an L indicates a long double argument.
6. A conversion character, which indicates the type of data to be converted and printed.
A one-to-one correlation must exist between each specification encountered and each item
in the item list.
The available flags are:
- Causes the data to be left-justified within its output field. Normally, the
data is right-justified.
+ Causes all signed data to begin with a sign (+ or -). Normally, only
negative values have signs.
blank Causes a blank to be inserted before a positive signed value. This is used
to line up positive and negative values in columnar data. Otherwise, the
first digit of a positive value is lined up with the negative sign of a
negative value. If the blank and + flags both appear, the blank flag is
ignored.
# Causes the data to be written in an alternate form. Refer to the
descriptions of the conversion characters below for details concerning the
effects of this flag.
0 For d, i, o, u, x, X, e, E, f, g, and G conversions, leading zeros (following any
indication of sign or base) are used to pad to the field width. No space
padding is performed. If the 0 and - flag s both appear, the 0 flag is
ignored. The 0 flag is also ignored for d, i, o, u, x, and X conversions if a
precision is specified.
A
field width , if specified, determines the minimum number of spaces allocated to the
output field for the particular piece of data being printed. If the data happens to be smaller
than the field width, the data is blank-padded on the left (or on the right, if the - flag is
specified) to fill the field. If the data is larger than
field width , the field width is
simply expanded to accommodate the data. An insufficient
field width never causes data
to be truncated. If
field width is not specified, the resulting field is made just large
enough to hold the data.
The
precision is a value that means different things depending on the conversion
character specified. Refer to the descriptions of the conversion characters below for more
details.
NOTE A field width or precision may be replaced by an asterisk (*). If so, the
next item in the item list is fetched, and its value is used as the
field width
or precision . The item fetched must be an integer.
Conversion Characters
Conversion characters specify the type of data to expect in the item list and cause the data
