Built-in Functions
Li
f,g or e
Matches a long signed or unsigned integer. The corresponding
argument shall be a pointer to a long signed or unsigned integer.
Matches a floating point number in decimal or exponential format.
The corresponding argument shall be a pointer to a float.
[ Matches a non-empty sequence of characters from a set of
expected characters. The sequence of characters included in the
set are made up of all character following the left bracket ([) up to
the matching right bracket (]). Unless the first character after the
left bracket is a ^, in which case the set of characters contain all
characters that do not appear between the brackets. If a -
character is in the set and is not the first or second, where the
first is a ^, nor the last character, then the set includes all
characters from the character before the - to the character after
the -.
For example, %[a-z] would include all characters from a to z in
the set and %[^a-z] would exclude all characters from a to z from
the set. The corresponding argument shall be a pointer to the
initial character of an array long enough to accept the sequence
and a terminating null character, which will be added
automatically.
n
Assigns the number of characters read thus far by the call to
scanf() to the corresponding argument. The corresponding
argument shall be a pointer to an unsigned integer.
An optional assignment-suppressing character (*) can be used
after the format specifier to indicate that the conversion
specification is to be done, but not saved into a corresponding
variable. In this case, no corresponding argument variable
should be passed to the scanf() function.
A string composed of ordinary non-white space characters is
executed by reading the next character of the string. If one of the
inputted characters differs from the string, the function fails and
exits. If a white-space character precedes the ordinary non-white
space characters, then white-space characters are first read in
until a non-white space character is read.
White-space characters are skipped, except for the conversion
specifiers [, c or n, unless a white-space character precedes the [
or c specifiers.
