A Package modified in ssnprintf_2.2/README 644 312 310 33607 7173331667 7271 snprintf.c - a portable implementation of snprintf, including vsnprintf.c, asnprintf, vasnprintf, asprintf, vasprintf snprintf is a routine to convert numeric and string arguments to formatted strings. It is similar to sprintf(3) provided in a system's C library, yet it requires an additional argument - the buffer size - and it guarantees never to store anything beyond the given buffer, regardless of the format or arguments to be formatted. Some newer operating systems do provide snprintf in their C library, but many do not or do provide an inadequate (slow or idiosyncratic) version, which calls for a portable implementation of this routine. Author Mark Martinec , April 1999, June 2000 Copyright © 1999, Mark Martinec Terms and conditions ... This program is free software; you can redistribute it and/or modify it under the terms of the Frontier Artistic License which comes with this Kit. Features * careful adherence to specs regarding flags, field width and precision; * good performance for large string handling (large format, large argument or large paddings). Performance is similar to system's sprintf and in several cases significantly better (make sure you compile with optimizations turned on, tell the compiler the code is strict ANSI if necessary to give it more freedom for optimizations); * return value semantics per ISO/IEC 9899:1999 ("ISO C99"); * written in standard ISO/ANSI C - requires an ANSI C compiler. Supported conversion specifiers and data types This snprintf only supports the following conversion specifiers: s, c, d, o, u, x, X, p (and synonyms: i, D, U, O - see below) with flags: '-', '+', ' ', '0' and '#'. An asterisk is supported for field width as well as precision. Length modifiers 'h' (short int), 'l' (long int), and 'll' (long long int) are supported. NOTE: If macro SNPRINTF_LONGLONG_SUPPORT is not defined (default) the length modifier 'll' is recognized but treated the same as 'l', which may cause argument value truncation! Defining SNPRINTF_LONGLONG_SUPPORT requires that your system's sprintf also handles length modifier 'll'. long long int is a language extension which may not be portable. Conversion of numeric data (conversion specifiers d, o, u, x, X, p) with length modifiers (none or h, l, ll) is left to the system routine sprintf, but all handling of flags, field width and precision as well as c and s conversions is done very carefully by this portable routine. If a string precision (truncation) is specified (e.g. %.8s) it is guaranteed the string beyond the specified precision will not be referenced. Length modifiers h, l and ll are ignored for c and s conversions (data types wint_t and wchar_t are not supported). The following common synonyms for conversion characters are supported: * i is a synonym for d * D is a synonym for ld, explicit length modifiers are ignored * U is a synonym for lu, explicit length modifiers are ignored * O is a synonym for lo, explicit length modifiers are ignored The D, O and U conversion characters are nonstandard, they are supported for backward compatibility only, and should not be used for new code. The following is specifically not supported: * flag ' (thousands' grouping character) is recognized but ignored * numeric conversion specifiers: f, e, E, g, G and synonym F, as well as the new a and A conversion specifiers * length modifier 'L' (long double) and 'q' (quad - use 'll' instead) * wide character/string conversions: lc, ls, and nonstandard synonyms C and S * writeback of converted string length: conversion character n * the n$ specification for direct reference to n-th argument * locales It is permitted for str_m to be zero, and it is permitted to specify NULL pointer for resulting string argument if str_m is zero (as per ISO C99). The return value is the number of characters which would be generated for the given input, excluding the trailing null. If this value is greater or equal to str_m, not all characters from the result have been stored in str, output bytes beyond the (str_m-1) -th character are discarded. If str_m is greater than zero it is guaranteed the resulting string will be null-terminated. NOTE that this matches the ISO C99, OpenBSD, and GNU C library 2.1, but is different from some older and vendor implementations, and is also different from XPG, XSH5, SUSv2 specifications. For historical discussion on changes in the semantics and standards of snprintf see printf(3) man page in the Linux programmers manual. Routines asprintf and vasprintf return a pointer (in the ptr argument) to a buffer sufficiently large to hold the resulting string. This pointer should be passed to free(3) to release the allocated storage when it is no longer needed. If sufficient space cannot be allocated, these functions will return -1 and set ptr to be a NULL pointer. These two routines are a GNU C library extensions (glibc). Routines asnprintf and vasnprintf are similar to asprintf and vasprintf, yet, like snprintf and vsnprintf counterparts, will write at most str_m-1 characters into the allocated output string, the last character in the allocated buffer then gets the terminating null. If the formatted string length (the return value) is greater than or equal to the str_m argument, the resulting string was truncated and some of the formatted characters were discarded. These routines present a handy way to limit the amount of allocated memory to some sane value.

1999-06-30 V1.3 Mark Martinec <mark.martinec@ijs.si>
  • fixed runaway loop (eventually crashing when str_l wraps beyond 2^31) while copying format string without conversion specifiers to a buffer that is too short (thanks to Edwin Young <edwiny@autonomy.com> for spotting the problem);
  • added macros PORTABLE_SNPRINTF_VERSION_(MAJOR|MINOR) to snprintf.h
2000-02-14 V2.0 (never released) Mark Martinec <mark.martinec@ijs.si>
  • relaxed license terms: The Artistic License now applies. You may still apply the GNU GENERAL PUBLIC LICENSE as was distributed with previous versions, if you prefer;
  • changed REVISION HISTORY dates to use ISO 8601 date format;
  • added vsnprintf (patch also independently proposed by Caolán McNamara 2000-05-04, and Keith M Willenson 2000-06-01)
2000-06-27 V2.1 Mark Martinec <mark.martinec@ijs.si>
  • removed POSIX check for str_m < 1; value 0 for str_m is allowed by ISO C99 (and GNU C library 2.1) (pointed out on 2000-05-04 by Caolán McNamara, caolan@ csn dot ul dot ie). Besides relaxed license this change in standards adherence is the main reason to bump up the major version number;

  • autoconf contributed by Caolán McNamara
2000-10-06 V2.2 Mark Martinec <mark.martinec@ijs.si>
  • BUG FIX: the %c conversion used a temporary variable that was no longer in scope when referenced, possibly causing incorrect resulting character;
  • BUG FIX: make precision and minimal field width unsigned to handle huge values (2^31 <= n < 2^32) correctly; also be more careful in the use of signed/unsigned/size_t internal variables -- probably more careful than many vendor implementations, but there may still be a case where huge values of str_m, precision or minimal field could cause incorrect behaviour;
  • use separate variables for signed/unsigned arguments, and for short/int, long, and long long argument lengths to avoid possible incompatibilities on certain computer architectures. Also use separate variable arg_sign to hold sign of a numeric argument, to make code more transparent;
  • some fiddling with zero padding and "0x" to make it Linux compatible;
  • systematically use macros fast_memcpy and fast_memset instead of case-by-case hand optimization; determine some breakeven string lengths for different architectures;
  • terminology change: format -> conversion specifier, C9x -> ISO/IEC 9899:1999 ("ISO C99"), alternative form -> alternate form, data type modifier -> length modifier;
  • several comments rephrased and new ones added;
  • make compiler not complain about 'credits' defined but not used;

Other implementations of snprintf

I am aware of some other (more or less) portable implementations of snprintf. I do not claim they are free software - please refer to their respective copyright and licensing terms. If you know of other versions please let me know.

In retrospect, it appears that a lot of effort was wasted by many people for not being aware of what others are doing. Sigh.

Defining * SNPRINTF_LONGLONG_SUPPORT requires that your system's sprintf also * handles length modifier 'll'. long long int is a language extension * which may not be portable. * * Conversion of numeric data (conversion specifiers d, u, o, x, X, p) * with length modifiers (none or h, l, ll) is left to the system routine * sprintf, but all handling of flags, field width and precision as well as * c and s conversions is done very carefully by this portable routine. * If a string precision (truncation) is specified (e.g. %.8s) it is * guaranteed the string beyond the specified precision will not be referenced. * * Length modifiers h, l and ll are ignored for c and s conversions (data * types wint_t and wchar_t are not supported). * * The following common synonyms for conversion characters are supported: * - i is a synonym for d * - D is a synonym for ld, explicit length modifiers are ignored * - U is a synonym for lu, explicit length modifiers are ignored * - O is a synonym for lo, explicit length modifiers are ignored * The D, O and U conversion characters are nonstandard, they are supported * for backward compatibility only, and should not be used for new code. * * The following is specifically NOT supported: * - flag ' (thousands' grouping character) is recognized but ignored * - numeric conversion specifiers: f, e, E, g, G and synonym F, * as well as the new a and A conversion specifiers * - length modifier 'L' (long double) and 'q' (quad - use 'll' instead) * - wide character/string conversions: lc, ls, and nonstandard * synonyms C and S * - writeback of converted string length: conversion character n * - the n$ specification for direct reference to n-th argument * - locales * * It is permitted for str_m to be zero, and it is permitted to specify NULL * pointer for resulting string argument if str_m is zero (as per ISO C99). * * The return value is the number of characters which would be generated * for the given input, excluding the trailing null. If this value * is greater or equal to str_m, not all characters from the result * have been stored in str, output bytes beyond the (str_m-1) -th character * are discarded. If str_m is greater than zero it is guaranteed * the resulting string will be null-terminated. * * NOTE that this matches the ISO C99, OpenBSD, and GNU C library 2.1, * but is different from some older and vendor implementations, * and is also different from XPG, XSH5, SUSv2 specifications. * For historical discussion on changes in the semantics and standards * of snprintf see printf(3) man page in the Linux programmers manual. * * Routines asprintf and vasprintf return a pointer (in the ptr argument) * to a buffer sufficiently large to hold the resulting string. This pointer * should be passed to free(3) to release the allocated storage when it is * no longer needed. If sufficient space cannot be allocated, these functions * will return -1 and set ptr to be a NULL pointer. These two routines are a * GNU C library extensions (glibc). * * Routines asnprintf and vasnprintf are similar to asprintf and vasprintf, * yet, like snprintf and vsnprintf counterparts, will write at most str_m-1 * characters into the allocated output string, the last character in the * allocated buffer then gets the terminating null. If the formatted string * length (the return value) is greater than or equal to the str_m argument, * the resulting string was truncated and some of the formatted characters * were discarded. These routines present a handy way to limit the amount * of allocated memory to some sane value. * * AVAILABILITY * http://www.ijs.si/software/snprintf/ * * REVISION HISTORY * 1999-04 V0.9 Mark Martinec * - initial version, some modifications after comparing printf * man pages for Digital Unix 4.0, Solaris 2.6 and HPUX 10, * and checking how Perl handles sprintf (differently!); * 1999-04-09 V1.0 Mark Martinec * - added main test program, fixed remaining inconsistencies, * added optional (long long int) support; * 1999-04-12 V1.1 Mark Martinec * - support the 'p' conversion (pointer to void); * - if a string precision is specified * make sure the string beyond the specified precision * will not be referenced (e.g. by strlen); * 1999-04-13 V1.2 Mark Martinec * - support synonyms %D=%ld, %U=%lu, %O=%lo; * - speed up the case of long format string with few conversions; * 1999-06-30 V1.3 Mark Martinec * - fixed runaway loop (eventually crashing when str_l wraps * beyond 2^31) while copying format string without * conversion specifiers to a buffer that is too short * (thanks to Edwin Young for * spotting the problem); * - added macros PORTABLE_SNPRINTF_VERSION_(MAJOR|MINOR) * to snprintf.h * 2000-02-14 V2.0 (never released) Mark Martinec * - relaxed license terms: The Artistic License now applies. * You may still apply the GNU GENERAL PUBLIC LICENSE * as was distributed with previous versions, if you prefer; * - changed REVISION HISTORY dates to use ISO 8601 date format; * - added vsnprintf (patch also independently proposed by * Caolan McNamara 2000-05-04, and Keith M Willenson 2000-06-01) * 2000-06-27 V2.1 Mark Martinec * - removed POSIX check for str_m<1; value 0 for str_m is * allowed by ISO C99 (and GNU C library 2.1) - (pointed out * on 2000-05-04 by Caolan McNamara, caolan@ csn dot ul dot ie). * Besides relaxed license this change in standards adherence * is the main reason to bump up the major version number; * - added nonstandard routines asnprintf, vasnprintf, asprintf, * vasprintf that dynamically allocate storage for the * resulting string; these routines are not compiled by default, * see comments where NEED_V?ASN?PRINTF macros are defined; * - autoconf contributed by Caolan McNamara * 2000-10-06 V2.2 Mark Martinec * - BUG FIX: the %c conversion used a temporary variable * that was no longer in scope when referenced, * possibly causing incorrect resulting character; * - BUG FIX: make precision and minimal field width unsigned * to handle huge values (2^31 <= n < 2^32) correctly; * also be more careful in the use of signed/unsigned/size_t * internal variables - probably more careful than many * vendor implementations, but there may still be a case * where huge values of str_m, precision or minimal field * could cause incorrect behaviour; * - use separate variables for signed/unsigned arguments, * and for short/int, long, and long long argument lengths * to avoid possible incompatibilities on certain * computer architectures. Also use separate variable * arg_sign to hold sign of a numeric argument, * to make code more transparent; * - some fiddling with zero padding and "0x" to make it * Linux compatible; * - systematically use macros fast_memcpy and fast_memset * instead of case-by-case hand optimization; determine some * breakeven string lengths for different architectures; * - terminology change: 'format' -> 'conversion specifier', * 'C9x' -> 'ISO/IEC 9899:1999 ("ISO C99")', * 'alternative form' -> 'alternate form', * 'data type modifier' -> 'length modifier'; * - several comments rephrased and new ones added; * - make compiler not complain about 'credits' defined but * not used; */ /* Define HAVE_SNPRINTF if your system already has snprintf and vsnprintf. * * If HAVE_SNPRINTF is defined this module will not produce code for * snprintf and vsnprintf, unless PREFER_PORTABLE_SNPRINTF is defined as well, * causing this portable version of snprintf to be called portable_snprintf * (and portable_vsnprintf). */ /* #define HAVE_SNPRINTF */ /* Define PREFER_PORTABLE_SNPRINTF if your system does have snprintf and * vsnprintf but you would prefer to use the portable routine(s) instead. * In this case the portable routine is declared as portable_snprintf * (and portable_vsnprintf) and a macro 'snprintf' (and 'vsnprintf') * is defined to expand to 'portable_v?snprintf' - see file snprintf.h . * Defining this macro is only useful if HAVE_SNPRINTF is also defined, * but does does no harm if defined nevertheless. */ /* #define PREFER_PORTABLE_SNPRINTF */ /* Define SNPRINTF_LONGLONG_SUPPORT if you want to support * data type (long long int) and length modifier 'll' (e.g. %lld). * If undefined, 'll' is recognized but treated as a single 'l'. * * If the system's sprintf does not handle 'll' * the SNPRINTF_LONGLONG_SUPPORT must not be defined! * * This is off by default as (long long int) is a language extension. */ /* #define SNPRINTF_LONGLONG_SUPPORT */ /* Define NEED_SNPRINTF_ONLY if you only need snprintf, and not vsnprintf. * If NEED_SNPRINTF_ONLY is defined, the snprintf will be defined directly, * otherwise both snprintf and vsnprintf routines will be defined * and snprintf will be a simple wrapper around vsnprintf, at the expense * of an extra procedure call. */ /* #define NEED_SNPRINTF_ONLY */ /* Define NEED_V?ASN?PRINTF macros if you need library extension * routines asprintf, vasprintf, asnprintf, vasnprintf respectively, * and your system library does not provide them.

Note that snprintf.c and snprintf.h are just symbolic links to a parent directory. 2. ./configure make make install 3a. set up your program with autoconf along the lines of this example dnl confirms that you have a working snprintf AC_caolan_FUNC_SNPRINTF if test x$ac_cv_func_snprintf = xno; then dnl will add -lsnprintf to your libs if it exists and defines HAVE_PKG_snprintf AC_caolan_CHECK_PACKAGE(snprintf,snprintf,snprintf,snprintf.h,,NO_SNPRINTF=true) if test x$NO_SNPRINTF = xtrue; then AC_MSG_WARN(Couldn't find a suitable snprintf implementation!\n Try at http://www.ijs.si/software/snprintf/) fi fi dnl AC_caolan_FUNC_SNPRINTF and AC_caolan_CHECK_PACKAGE can be gotten dnl at http://www.csn.ul.ie/~caolan/publink/autoconf dnl place then in your aclocal dir (/usr/local/share/aclocal perhaps) dnl and run aclocal before running autoconf, when running autoheader dnl various symbols will be missing, add the missing ones as dnl #undef symbol lines into acconfig.h dnl dnl you then should have in your source code... dnl #ifdef HAVE_PKG_snprintf dnl #include dnl #endif dnl I place mine in acconfig.h and include config.h in every source file. 3b.
