- UnixLib 3.8
- ~~~~~~~~~~~
-
- The following details some of the more noticable changes that have
- been made to UnixLib since version 3.7b.
-
- * NetLib code has been tested and works. It is no longer an option to
- leave out this code.
-
- * 'printf' and 'scanf' have been ported from BSD 4.3. 'printf' output is
- now ANSI conformat and floating point numbers are correctly rounded
- and very accurate. 'scanf' now supports scan-sets.
-
- * 'strtod' has been ported from BSD 4.3. It is a very accurate
- implementation.
-
- * 'stpcpy', 'stpncpy' are new functions. These copy a string and return a
- pointer to the terminating null character.
-
- * Character Localisation (locale) has been implemented and uses the
- Territory Manager for the underlying features. Functions include
- 'localeconv', 'setlocale', 'strcoll' and 'strxfrm'.
-
- * The time functions have been re-written. These now use the Territory
- Manager for underlying support, as well as being integrated with the
- locale support. Daylight saving time is now supported and POSIX features
- have been added to 'strftime'.
-
- * The ctype functions now support locale.
-
- * Math support has been extended to provide most of the features of libm.
- New functions include 'cbrt', 'erf', 'expm1', 'fmod', 'ilogb', 'j0',
- 'j1', 'jn', 'lgamma', 'log1p', 'logb', 'nextafter', 'remainder',
- 'rem_pio2', 'rint', 'scalbn', 'significand', 'isinf', 'isnan',
- 'finite', 'copysign'. Existing math functions now produce answers
- accurate to 1 unit in the last place.
-
- * Standard input/output has been re-written. A restriction of the number of
- stdio streams that can be opened has been removed. The new limit is
- memory, the underlying operating system (RISC OS) and the number of
- file descriptors available. Many bugs have been fixed.
-
- * The code behind the implemention of file descriptors has been largely
- re-written. Currently, the maximum number of file descriptors that
- can be opened is set at 64, but it is easy to extend this to millions.
- Many bugs have been fixed.
-
- * The directory reading functions have been re-written. The number of
- directories that can be opened using 'opendir' is now limited by memory.
-
- * New POSIX features have been added: 'fnmatch', 'getopt', 'getsubopt',
- 'glob' and 'uname'.
-
- * Command line parsing has been improved. Filenames of the form
- '<test$dir>.fred' are no longer interpreted as redirecting standard input
- to read from the file 'test$dir>.fred'.
-
- * The mmap associated function calls have been implemented for RISC OS
- users that have dynamic area support.
-
- * Malloc has been updated to Doug Lea's latest version. This will use
- mmap for large allocations (on RISC OS versions that support it).
-
- * 'strtol', 'strtoul' are now accurate
-
- * fcrypt has been added.
-
- * The majority of functions provided by the SharedCLibrary header file
- kernel.h have been implemented.
-
- * 'getenv' has been re-written. Environment variables are now correctly
- passed to the child process.
-
- * Extra safeguards have been added to prevent the stack backtrace from
- crashing.
-
- * The header file termio.h has been replaced by the POSIX standard version
- termios.h.
-
- * Filename translation can be turned on or off at run-time by setting a
- system variable.
-
- * Added and implemented complex.h and fenv.h.
-
- * Removed 1024 character command line restriction.
-
- * Improved command line argument parser.
