and -o or --operating-system.
'uname -a' now outputs -i and -o information at the end.
New uname option --kernel-version is an alias for -v.
Uname option --release has been renamed to --kernel-release,
and --sysname has been renamed to --kernel-name;
the old options will work for a while, but are no longer documented.
Remove list of options in comment, which wasn't
worth maintaining separately from usage().
(print_element): Move definition up, avoiding the need for
declaration and allowing inlining on some platforms.
Keep track of whether something has been printed; this is more
natural than modifying `toprint'.
(PRINT_KERNEL_NAME): Renamed from PRINT_SYSNAME.
(PRINT_KERNEL_RELEASE): Renamed from PRINT_RELEASE.
(PRINT_KERNEL_VERSION): Renamed from PRINT_VERSION.
(PRINT_HARDWARE_PLATFORM, PRINT_OPERATING_SYSTEM): New macros.
(toprint): Remove global var; now local in `main'.
(long_options, usage, main): Implement changes described in NEWS.
Reorder options to reflect output order.
(main): Use buffers one byte longer, for compatibility with Solaris 8.
Output newline at end. -a sets `toprint' to -1 now; this is simpler.
Do not bother invoking system calls like uname if the resulting
information does not need to be printed.
Do not fail if sysinfo fails; just print "unknown".
fix the HAVE_GETCWD_NULL code to behave more like the
!HAVE_GETCWD_NULL code used to.
Include "xalloc.h".
(xgetcwd): Do not return NULL when memory is exhausted; instead,
invoke xalloc_die.
Use ssize_t, not int, to store result of readlink.
Check for ssize_t overflow as well as size_t overflow,
as POSIX says the result of readlink is implementation-defined
when ssize_t overflows.
Remove unnecessary cast to char*.
Use free+malloc instead of realloc, as the storage doesn't need
to be preserved and it's clearer and can be more efficient that way.
(SIZE_MAX, SSIZE_MAX): New macros, if <limits.h> doesn't declare.
like the HAVE_GETCWD_NULL code.
Include pathmax.h if not HAVE_GETCWD.
Do not include xalloc.h.
(INITIAL_BUFFER_SIZE): New symbol.
Do not use xmalloc / xrealloc, since the caller is responsible for
handling errors. Preserve errno around `free' during failure.
Do not overrun buffer when using getwd.
