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>>, <<l>>, and <<L>> are optional size characters which - override the default way that <<scanf>> interprets the - data type of the corresponding argument. - - -.Modifier Type(s) -. h d, i, o, u, x convert input to short, -. store in short object -. -. h D, I, O, U, X no effect -. e, f, c, s, n, p -. -. l d, i, o, u, x 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, n, p -. -.

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. ANSI C leaves the details - to each implementation; this implementation treats - <<%p>> exactly the same as <<%U>>. 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: - -.
