The scanf( ) function can handle a format string that enables the system to process an element of the input stream for storage at a specific pointer location.
PAGE 412
scanf(3) Guardian Native C Library Calls Reference Manual 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 characters are accepted and the corresponding pointer parameter should be an array of type char. The normal skip over white space is suppressed.
PAGE 413
Guardian Native C Library Calls (s) scanf(3) s Accepts a string of characters. The input field ends with a white-space character. If width is given, the corresponding pointer parameter refers to a character array and the indicated number of type char values are read. A string of type char values is written to the array. The array must be large enough to contain the output string with a terminating null byte appended. S Accepts a string of characters. The input field ends with a white-space character.
PAGE 414
scanf(3) Guardian Native C Library Calls Reference Manual Unless there is a match in the conversion specification, trailing white space (including a newline character) is not read. The success of literal matches and suppressed assignments cannot be directly determined. The scanf( ) function returns the number of successfully matched and assigned input items. NOTES This function supports both IEEE Std 754-1985 floating-point and Tandem floating-point values in the native environment.

Guardian Native C Library Calls (t - z) vsnprintf(3) — The maximum number of bytes to be printed from a string in the s or S conversion. A field precision can be indicated by an * (asterisk) instead of a digit string. In this case, an integer (int) value parameter supplies the field precision. The value parameter converted for output is not fetched until the conversion letter is reached, so the parameters specifying field width or precision must appear before the value (if any) to be converted.

vsnprintf(3) 7−54 Guardian Native C Library Calls Reference Manual o Accepts an integer (int) value and converts it to unsigned octal notation. The precision specifies the minimum number of digits to appear. If the value being converted can be represented in fewer digits, it is expanded with leading zeros. The default precision is 1. The result of converting a 0 (zero) value with a precision of 0 (zero) is a null string.
PAGE 569
Guardian Native C Library Calls (t - z) vsnprintf(3) s Accepts a pointer to an array of char type. Bytes from the array are printed until a null character is encountered or the number of characters indicated by the precision is reached. If no precision is specified, all characters up to the first null character are printed. If the precision is not specified or is greater than the size of the array, then the array must be terminated by a null byte.

vsnprintf(3) Guardian Native C Library Calls Reference Manual RETURN VALUES Upon successful completion, this function returns the number of bytes that would have been stored had n been sufficiently large (not counting the terminating null character). Otherwise, a negative value is returned. Thus, the null-terminated output has been completely stored if and only if the returned value is nonnegative and less than n.
