+ plp_unsafe_snprintf( char *buffer, int len, const char *format,...)
+ its horribly unsafe companion that does NOT protect you from
+ the printing of evil control characters, but may be necessary
+ See the man page documentation below
+
+ This version of snprintf was developed originally for printing
+ on a motley collection of specialized hardware that had NO IO
+ library. Due to contractual restrictions, a clean room implementation
+ of the printf() code had to be developed.
+
+ The method chosen for printf was to be as paranoid as possible,
+ as these platforms had NO memory protection, and very small
+ address spaces. This made it possible to try to print
+ very long strings, i.e. - all of memory, very easily. To guard
+ against this, all printing was done via a buffer, generous enough
+ to hold strings, but small enough to protect against overruns,
+ etc.
+
+ Strangely enough, this proved to be of immense importance when
+ SPRINTFing to a buffer on a stack... The rest, of course, is
+ well known, as buffer overruns in the stack are a common way to
+ do horrible things to operating systems, security, etc etc.
+
+ This version of snprintf is VERY limited by modern standards.

+ NAME
+ snprintf, plp_vsnprintf - formatted output conversion
+
+ SYNOPSIS
+ #include <stdio.h>
+ #include <stdarg.h>
+
+ int
+ snprintf(const char *format, size_t size, va_list ap);
+ 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. The effect of padding the %p format
+ with zeros (either by the `0' flag or by specifying a precision), and the
+ benign effect (i.e., none) of the `#' flag on %n and %p conversions, as
+ well as other nonsensical combinations such as %Ld, are not standard;
+ such combinations should be avoided.
- b) accompany the distribution with the machine-readable source of
- the Package with your modifications.
+ The typedef names quad_t and u_quad_t are infelicitous.
- c) give non-standard executables non-standard names, and clearly
- document the differences in manual pages (or equivalent), together
- with instructions on where to get the Standard Version.

- d) make other distribution arrangements with the Copyright Holder.

- * Patrick Powell Tue Apr 11 09:48:21 PDT 1995
- * A bombproof version of doprnt (dopr) included.
- * Sigh. This sort of thing is always nasty do deal with. Note that
- * the version here does not include floating point...
- *
- * plp_snprintf() is used instead of sprintf() as it does limit checks
- * for string length. This covers a nasty loophole.
- *
- * The other functions are there to prevent NULL pointers from
- * causing nast effects.
