++ int ++ plp_unsafe_snprintf(const char *format, size_t size, va_list ap); ++ ++ AKA snprintf and unsafe_snprintf in the documentation below ++ ++ int ++ vsnprintf(char *str, size_t size, const char *format, va_list ap); ++ int ++ unsafe_vsnprintf(char *str, size_t size, const char *format, va_list ap); ++ ++ AKA vsnprintf and unsafe_vsnprintf in the documentation below ++ ++ (Multithreaded Safe) ++ ++ DESCRIPTION ++ The printf() family of functions produces output according to ++ a format as described below. Snprintf(), and vsnprintf() ++ write to the character string str. These functions write the ++ output under the control of a format string that specifies ++ how subsequent arguments (or arguments accessed via the ++ variable-length argument facilities of stdarg(3)) are converted ++ for output. These functions return the number of characters ++ printed (not including the trailing `\0' used to end output ++ to strings). Snprintf() and vsnprintf() will write at most ++ size-1 of the characters printed into the output string (the ++ size'th character then gets the terminating `\0'); if the ++ return value is greater than or equal to the size argument, ++ the string was too short and some of the printed characters ++ were discarded. The size or str may be given as zero to find ++ out how many characters are needed; in this case, the str ++ argument is ignored. ++ ++ By default, the snprintf function will not format control ++ characters (except new line and tab) in strings. This is a ++ safety feature that has proven to be extremely critical when ++ using snprintf for secure applications and when debugging. ++ If you MUST have control characters formatted or printed, ++ then use the unsafe_snprintf() and unsafe_vsnprintf() and on ++ your own head be the consequences. You have been warned. ++ ++ There is one exception to the comments above, and that is ++ the "%c" (character) format. It brutally assumes that the ++ user will have performed the necessary 'isprint()' or other ++ checks and uses the integer value as a character. ++ ++ The format string is composed of zero or more directives: ++ ordinary characters (not %), which are copied unchanged to ++ the output stream; and conversion specifications, each ++ of which results in fetching zero or more subsequent arguments. ++ Each conversion specification is introduced by the character ++ %. The arguments must correspond properly (after type promotion) ++ with the conversion specifier. After the %, the following ++ appear in sequence: ++ ++ o Zero or more of the following flags: ++ ++ - A zero `0' character specifying zero padding. For ++ all conversions except n, the converted value is padded ++ on the left with zeros rather than blanks. If a ++ precision is given with a numeric conversion (d, i, ++ o, u, i, x, and X), the `0' flag is ignored. ++ ++ - A negative field width flag `-' indicates the converted ++ value is to be left adjusted on the field boundary. Except ++ for n conversions, the converted value is padded on ++ the right with blanks, rather than on the left with ++ blanks or zeros. A `-' overrides a `0' if both are ++ given. ++ ++ - A space, specifying that a blank should be left before ++ a positive number produced by a signed conversion (d, e, E, f, ++ g, G, or i). ++ ++ - A `+' character specifying that a sign always be placed ++ before a number produced by a signed conversion. A `+' overrides ++ a space if both are used. ++ ++ o An optional decimal digit string specifying a minimum ++ field width. If the converted value has fewer ++ characters than the field width, it will be padded ++ with spaces on the left (or right, if the ++ left-adjustment flag has been given) to fill out ++ the field width. ++ ++ o An optional precision, in the form of a period `.' followed ++ by an optional digit string. If the digit string ++ is omitted, the precision is taken as zero. This ++ gives the minimum number of digits to appear for ++ d, i, o, u, x, and X conversions, the number of ++ digits to appear after the decimal-point for e, ++ E, and f conversions, the maximum number of ++ significant digits for g and G conversions, or ++ the maximum number of characters to be printed ++ from a string for s conversions. ++ ++ o The optional character h, specifying that a following d, ++ i, o, u, x, or X conversion corresponds to a short ++ int or unsigned short int argument, or that a ++ following n conversion corresponds to a pointer ++ to a short int argument. ++ ++ o The optional character l (ell) specifying that a following ++ d, i, o, u, x, or X conversion applies to a pointer ++ to a long int or unsigned long int argument, or ++ that a following n conversion corresponds to a ++ pointer to a long int argument. ++ ++ o The optional character q, specifying that a following d, ++ i, o, u, x, or X conversion corresponds to a quad_t ++ or u_quad_t argument, or that a following n ++ conversion corresponds to a quad_t argument. ++ This value is always printed in HEX notation. Tough. ++ quad_t's are an OS system implementation, and should ++ not be allowed. ++ ++ o The character L specifying that a following e, E, f, g, ++ or G conversion corresponds to a long double ++ argument. ++ ++ o A character that specifies the type of conversion to be applied. ++ ++ ++ A field width or precision, or both, may be indicated by an asterisk `*' ++ instead of a digit string. In this case, an int argument supplies the ++ field width or precision. A negative field width is treated as a left ++ adjustment flag followed by a positive field width; a negative precision ++ is treated as though it were missing. ++ ++ The conversion specifiers and their meanings are: ++ ++ diouxX The int (or appropriate variant) argument is converted to signed ++ decimal (d and i), unsigned octal (o), unsigned decimal ++ (u), or unsigned hexadecimal (x and X) notation. The ++ letters abcdef are used for x conversions; the letters ++ ABCDEF are used for X conversions. The precision, if ++ any, gives the minimum number of digits that must ++ appear; if the converted value requires fewer digits, ++ it is padded on the left with zeros. ++ ++ eE The double argument is rounded and converted in the style ++ [-]d.ddde+-dd where there is one digit before the decimal-point ++ character and the number of digits after it is equal ++ to the precision; if the precision is missing, it is ++ taken as 6; if the precision is zero, no decimal-point ++ character appears. An E conversion uses the letter ++ E (rather than e) to introduce the exponent. ++ The exponent always contains at least two digits; if ++ the value is zero, the exponent is 00. ++ ++ f The double argument is rounded and converted to decimal notation ++ in the style [-]ddd.ddd, where the number of digits after the ++ decimal-point character is equal to the precision specification. ++ If the precision is missing, it is taken as 6; if the precision ++ is explicitly zero, no decimal-point character appears. If a ++ decimal point appears, at least one digit appears before it. ++ ++ g The double argument is converted in style f or e (or ++ E for G conversions). The precision specifies the ++ number of significant digits. If the precision is ++ missing, 6 digits are given; if the precision is zero, ++ it is treated as 1. Style e is used if the exponent ++ from its conversion is less than -4 or greater than ++ or equal to the precision. Trailing zeros are removed ++ from the fractional part of the result; a decimal ++ point appears only if it is followed by at least one ++ digit. ++ ++ c The int argument is converted to an unsigned char, ++ and the resulting character is written. ++ ++ s The ``char *'' argument is expected to be a pointer to an array ++ of character type (pointer to a string). Characters ++ from the array are written up to (but not including) ++ a terminating NUL character; if a precision is ++ specified, no more than the number specified are ++ written. If a precision is given, no null character ++ need be present; if the precision is not specified, ++ or is greater than the size of the array, the array ++ must contain a terminating NUL character. ++ ++ % A `%' is written. No argument is converted. The complete ++ conversion specification is `%%'. ++ ++ In no case does a non-existent or small field width cause truncation of a ++ field; if the result of a conversion is wider than the field width, the ++ field is expanded to contain the conversion result. ++ ++ EXAMPLES ++ To print a date and time in the form `Sunday, July 3, 10:02', where ++ weekday and month are pointers to strings: ++ ++ #include <stdio.h> ++ fprintf(stdout, "%s, %s %d, %.2d:%.2d\n", ++ weekday, month, day, hour, min); ++ ++ To print pi to five decimal places: ++ ++ #include <math.h> ++ #include <stdio.h> ++ fprintf(stdout, "pi = %.5f\n", 4 * atan(1.0)); ++ ++ To allocate a 128 byte string and print into it: ++ ++ #include <stdio.h> ++ #include <stdlib.h> ++ #include <stdarg.h> ++ char *newfmt(const char *fmt, ...) ++ { ++ char *p; ++ va_list ap; ++ if ((p = malloc(128)) == NULL) ++ return (NULL); ++ va_start(ap, fmt); ++ (void) vsnprintf(p, 128, fmt, ap); ++ va_end(ap); ++ return (p); ++ } ++ ++ SEE ALSO ++ printf(1), scanf(3) ++ ++ STANDARDS ++ Turkey C Standardization and wimpy POSIX folks did not define ++ snprintf or vsnprintf(). ++ ++ BUGS ++ The conversion formats %D, %O, and %U are not standard and are provided ++ only for backward compatibility.
