OSS Library Calls (t - v) vscanf(3)
—At followed by a d, i, o, u, x, X,orn conversion code character indicates that
the receiving variable is treated as a ptrdiff_t or the corresponding unsigned
integer type.
—Az followed by a d, i, o, u, x, X,orn conversion code character indicates that
the receiving variable is treated as a size_t or the corresponding unsigned integer
type.
• A conversion code character convcode that specifies the type of conversion to be
applied:
% Accepts a single % (percent sign) input at this point; no assignment is
done.
c Accepts a single character or a series of characters. If there is either no
width or a width of 1 in the conversion specification, one character is
accepted and the corresponding pointer parameter should be a type char
pointer. If there is a width greater than 1, the indicated number of char-
acters are accepted and the corresponding pointer parameter should be
an array of type char.
The normal skip over white space is suppressed. Use %1s rather than
%1c to read the next non-white-space character.
C or lc Accepts a single character or a series of characters and stores the data as
a wchar_t type.
If there is either no width or a width of 1 in the conversion specification,
one character is accepted and the corresponding pointer parameter
should be a type wchar_t pointer. If there is a width greater than 1, the
indicated number of characters are accepted and the corresponding
pointer parameter should be an array of type wchar_t.
The normal skip over white space is suppressed. Use %1S rather
than
%1C to
read the next non-white-space character.
For TNS/E systems only, the behavior of lc is the same as the behavior
of C.
d Accepts a decimal integer; the corresponding pointer parameter should
be an integer pointer.
a, A, e, E, f, F, g, G
Accepts a floating-point number. The next field is converted accord-
ingly and stored through the corresponding parameter, which should be a
pointer to a float. The input format must be the same as expected for the
subject sequence of the strtod( ) function. For more information, see the
strtod(3) reference page.
i Accepts a decimal integer unless:
— The first digit is a 0 (zero), in which case the integer is inter-
preted as an octal number.
— The first two characters are 0x or 0X, in which case the integer is
interpreted as a hexadecimal number.
The corresponding pointer parameter should be an integer pointer.
