Each field is interpreted according to - a format specifier passed to <<scanf>> in the format string at - <<*<[format]>>>. <<scanf>> stores the interpreted input from - each field at the address passed to it as the corresponding argument - following <[format]>. You must supply the same number of - format specifiers and address arguments as there are input fields. - - There must be sufficient address arguments for the given format - specifiers; if not the results are unpredictable and likely - disasterous. Excess address arguments are merely ignored. - - <<scanf>> often produces unexpected results if the input diverges from - an expected pattern. Since the combination of <<gets>> or <<fgets>> - followed by <<sscanf>> is safe and easy, that is the preferred way - to be certain that a program is synchronized with input at the end - of a line. - - <<fscanf>> and <<sscanf>> are identical to <<scanf>>, other than the - source of input: <<fscanf>> reads from a file, and <<sscanf>> - from a string. - - The routines <<_scanf_r>>, <<_fscanf_r>>, and <<_sscanf_r>> are reentrant - versions of <<scanf>>, <<fscanf>>, and <<sscanf>> that take an additional - first argument pointing to a reentrancy structure. - - The string at <<*<[format]>>> is a character sequence composed - of zero or more directives. Directives are composed of - one or more whitespace characters, non-whitespace characters, - and format specifications. - - Whitespace characters are blank (<< >>), tab (<<\t>>), or - newline (<<\n>>). - When <<scanf>> encounters a whitespace character in the format string - it will read (but not store) all consecutive whitespace characters - up to the next non-whitespace character in the input. - - Non-whitespace characters are all other ASCII characters except the - percent sign (<<%>>). When <<scanf>> encounters a non-whitespace - character in the format string it will read, but not store - a matching non-whitespace character. - - Format specifications tell <<scanf>> to read and convert characters - from the input field into specific types of values, and store then - in the locations specified by the address arguments. - - Trailing whitespace is left unread unless explicitly - matched in the format string. - - The format specifiers must begin with a percent sign (<<%>>) - and have the following form: - -. %[*][<[width]>][<[size]>]<[type]> - - Each format specification begins with the percent character (<<%>>). - The other fields are: - o+ - o * - an optional marker; if present, it suppresses interpretation and - assignment of this input field. - - o <[width]> - an optional maximum field width: a decimal integer, - which controls the maximum number of characters that - will be read before converting the current input field. If the - input field has fewer than <[width]> characters, <<scanf>> - reads all the characters in the field, and then - proceeds with the next field and its format specification. - - If a whitespace or a non-convertable character occurs - before <[width]> character are read, the characters up - to that character are read, converted, and stored. - Then <<scanf>> proceeds to the next format specification. - - o size - <<h>>, <<j>>, <<l>>, <<L>>, <<t>>, and <<z>> are optional size - characters which override the default way that <<scanf>> - interprets the data type of the corresponding argument. - - -.Modifier Type(s) -. hh d, i, o, u, x, n convert input to char, -. store in char object -. -. h d, i, o, u, x, n convert input to short, -. store in short object -. -. h D, I, O, U, X no effect -. e, f, c, s, p -. -. j d, i, o, u, x, n convert input to intmax_t, -. store in intmax_t object -. -. j all others no effect -. -. l d, i, o, u, x, n convert input to long, -. store in long object -. -. l e, f, g convert input to double -. store in a double object -. -. l D, I, O, U, X no effect -. c, s, p -. -. ll d, i, o, u, x, n convert to long long, -. store in long long -. -.

Here is a table of the conversion - characters: - - o+ - o % - No conversion is done; the percent character (<<%>>) is stored. - - o c - Scans one character. Corresponding <[arg]>: <<(char *arg)>>. - - o s - Reads a character string into the array supplied. - Corresponding <[arg]>: <<(char arg[])>>. - - o [<[pattern]>] - Reads a non-empty character string into memory - starting at <[arg]>. This area must be large - enough to accept the sequence and a - terminating null character which will be added - automatically. (<[pattern]> is discussed in the paragraph following - this table). Corresponding <[arg]>: <<(char *arg)>>. - - o d - Reads a decimal integer into the corresponding <[arg]>: <<(int *arg)>>. - - o D - Reads a decimal integer into the corresponding - <[arg]>: <<(long *arg)>>. - - o o - Reads an octal integer into the corresponding <[arg]>: <<(int *arg)>>. - - o O - Reads an octal integer into the corresponding <[arg]>: <<(long *arg)>>. - - o u - Reads an unsigned decimal integer into the corresponding - <[arg]>: <<(unsigned int *arg)>>. - - - o U - Reads an unsigned decimal integer into the corresponding <[arg]>: - <<(unsigned long *arg)>>. - - o x,X - Read a hexadecimal integer into the corresponding <[arg]>: - <<(int *arg)>>. - - o e, f, g - Read a floating-point number into the corresponding <[arg]>: - <<(float *arg)>>. - - o E, F, G - Read a floating-point number into the corresponding <[arg]>: - <<(double *arg)>>. - - o i - Reads a decimal, octal or hexadecimal integer into the - corresponding <[arg]>: <<(int *arg)>>. - - o I - Reads a decimal, octal or hexadecimal integer into the - corresponding <[arg]>: <<(long *arg)>>. - - o n - Stores the number of characters read in the corresponding - <[arg]>: <<(int *arg)>>. - - o p - Stores a scanned pointer.

Corresponding - <[arg]>: <<(void **arg)>>. - o- - - A <[pattern]> of characters surrounded by square brackets can be used - instead of the <<s>> type character. <[pattern]> is a set of - characters which define a search set of possible characters making up - the <<scanf>> input field. If the first character in the brackets is a - caret (<<^>>), the search set is inverted to include all ASCII characters - except those between the brackets. There is also a range facility - which you can use as a shortcut. <<%[0-9] >> matches all decimal digits. - The hyphen must not be the first or last character in the set. - The character prior to the hyphen must be lexically less than the - character after it. - - Here are some <[pattern]> examples: - o+ - o %[abcd] - matches strings containing only <<a>>, <<b>>, <<c>>, and <<d>>. - - o %[^abcd] - matches strings containing any characters except <<a>>, <<b>>, - <<c>>, or <<d>> - - o %[A-DW-Z] - matches strings containing <<A>>, <<B>>, <<C>>, <<D>>, <<W>>, - <<X>>, <<Y>>, <<Z>> - - o %[z-a] - matches the characters <<z>>, <<->>, and <<a>> - o- - - Floating point numbers (for field types <<e>>, <<f>>, <<g>>, <<E>>, - <<F>>, <<G>>) must correspond to the following general form: - -. [+/-] ddddd[.]ddd [E|e[+|-]ddd] - - where objects inclosed in square brackets are optional, and <<ddd>> - represents decimal, octal, or hexadecimal digits. - o- - -RETURNS - <<scanf>> returns the number of input fields successfully - scanned, converted and stored; the return value does - not include scanned fields which were not stored. - - If <<scanf>> attempts to read at end-of-file, the return - value is <<EOF>>. - - If no fields were stored, the return value is <<0>>. - - <<scanf>> might stop scanning a particular field before - reaching the normal field end character, or may - terminate entirely. - - <<scanf>> stops scanning and storing the current field - and moves to the next input field (if any) - in any of the following situations: - - O+ - o The assignment suppressing character (<<*>>) appears - after the <<%>> in the format specification; the current - input field is scanned but not stored. - - o <[width]> characters have been read (<[width]> is a - width specification, a positive decimal integer). - - o The next character read cannot be converted - under the the current format (for example, - if a <<Z>> is read when the format is decimal). - - o The next character in the input field does not appear - in the search set (or does appear in the inverted search set). - O- - - When <<scanf>> stops scanning the current input field for one of - these reasons, the next character is considered unread and - used as the first character of the following input field, or the - first character in a subsequent read operation on the input. - - <<scanf>> will terminate under the following circumstances: - - O+ - o The next character in the input field conflicts - with a corresponding non-whitespace character in the - format string. - - o The next character in the input field is <<EOF>>. - - o The format string has been exhausted. - O- - - When the format string contains a character sequence that is - not part of a format specification, the same character - sequence must appear in the input; <<scanf>> will - scan but not store the matched characters.
