Thu Jun 30 20:26:57 UTC 2016 Slackware 14.2 x86_64 stable is released! The long development cycle (the Linux community has lately been living in "interesting times", as they say) is finally behind us, and we're proud to announce the release of Slackware 14.2. The new release brings many updates and modern tools, has switched from udev to eudev (no systemd), and adds well over a hundred new packages to the system. Thanks to the team, the upstream developers, the dedicated Slackware community, and everyone else who pitched in to help make this release a reality. The ISOs are off to be replicated, a 6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD. Please consider supporting the Slackware project by picking up a copy from store.slackware.com. We're taking pre-orders now, and offer a discount if you sign up for a subscription. Have fun! :-)

|
-
|
|
-The intent of this document is to state the conditions under which a
|
|
-Package may be copied, such that the Copyright Holder maintains some
|
|
-semblance of artistic control over the development of the package,

|
|
-Definitions:
|
|
-
|
|
- "Package" refers to the collection of files distributed by the
|
|
- Copyright Holder, and derivatives of that collection of files
|
|
- created through textual modification.
|
|
-
|
|
- "Standard Version" refers to such a Package if it has not been
|
|
- modified, or has been modified in accordance with the wishes
|
|
- of the Copyright Holder as specified below.
|
|
-
|
|
- "Copyright Holder" is whoever is named in the copyright or
|
|
- copyrights for the package.
|
|
-
|
|
- "You" is you, if you are thinking about copying or distributing
|
|
- this Package.
|
|
-
|
|
- "Reasonable copying fee" is whatever you can justify on the
|
|
- basis of media cost, duplication charges, time of people involved,
|
|
- and so on. (You will not be required to justify it to the
|
|
- Copyright Holder, but only to the computing community at large
|
|
- as a market that must bear the fee.)
|
|
|
|
- "Freely Available" means that no fee is charged for the item
|
|
- itself, though there may be fees involved in handling the item.
|
|
- It also means that recipients of the item may redistribute it

-
|
|
-2. You may apply bug fixes, portability fixes and other modifications
|
|
-derived from the Public Domain or from the Copyright Holder. A Package
|
|
-modified in such a way shall still be considered the Standard Version.

|
-that you insert a prominent notice in each changed file stating how and
|
|
-when you changed that file, and provided that you do at least ONE of the
|
|
-following:

|
|
+ 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.

|
|
+ 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);
|
|
+ }

+ 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.
