Now we are always using the same text also for commands
which had still hardcoded descriptions or where we can't
use the standard print_usage_help_options macro.

Consolidate --help and --version descriptions. We are
now able to align them to the other options.
We changed include/c.h. The rest of this patch was
generated by sed, plus manually setting the right
alignment numbers. We do not change anything but
white spaces in the --help output.

The pid 0 is technically correct, but very confusing for end users. Use
getpid() in the messages.

This adds a concise description of a tool to its usage text.
A first form of this patch was proposed by Steven Honeyman
(see http://www.spinics.net/lists/util-linux-ng/msg09994.html).

This makes it match the license of the man pages.
While there, also tweak some other comment lines.

The unsuspecting user might use taskset -a mask command. Behavior then
is to exec with no affinity applied at all. Better handled by ignoring
all_tasks if no pid was given.

This is a preparation patch for chcpu. If a cpu should be added to
a cpu_set where the cpu doesn't fit into the cpu_set this got silently
ignored.
Since the cpu-list is user space provided it should be checked if cpus
are specified that are completely out of range of the system.
In order to do that add a parameter which specifies if cpulist_parse()
should fail if it parses a cpu-list with "impossible" cpus.
The current callers have been converted so they behave like before.

taskset.c should add these lines:
#include <sched.h> for sched_getaffinity, etc
#include <stddef.h> for size_t
#include <string.h> for memset

Add a new '-a' option to view/modify the CPU affinity for an entire
group of threads belonging to a given PID. We create two new
functions, print_affinity() and do_taskset() for code simplification.
Example:
zeus@jilguero:~/src/util-linux/schedutils$ ./taskset -a -p 01 3142
pid 3142's current affinity mask: 2
pid 3142's new affinity mask: 1
pid 3164's current affinity mask: 2
pid 3164's new affinity mask: 1
pid 854's current affinity mask: 2
pid 854's new affinity mask: 1

Solaris lacks err, errx, warn and warnx. This also means the err.h header
doesn't exist. Removed err.h include from all files, and included err.h from
c.h instead if it exists, otherwise alternatives are provided.

This patch replaces a few functions used throughout the source:
* Renames getnum (from schedutils) to strtol_or_err
* Moves strtosize (from lib/strtosize.c)
* Moves xstrncpy (from include/xstrncpy.h)
* Adds strnlen, strnchr and strndup if not available (remove it from libmount utils)
A few Makefile.am files were modified to compile accordingly along with trivial renaming
in schedutils source code.

The glibc already supports dynamically allocated CPU sets. We don't
have to maintains our private non-compatible implementation.
Signed-off-by: Karel Zak <kzak@redhat.com>
This patch makes the taskset command independent of the system's maximum
number of cpus (CONFIG_NR_CPUS). The maximum for CONFIG_NR_CPUS is a
moving target.
With this patch the size of the systems's cpumask_t is gotten from
sched_getaffinity(2).
This patch uses variable length bitmasks borrowed from Paul Jackson's
variable size bitmask routines (hence I kept his copyright notice).
This replaces the use of the glibc CPU_SETSIZE, CPU_SET, CPU_ZERO and
CPU_ISSET macros which depend on a hardcoded size for cpu_set_t.
(also fixes one little nit: the -V option is "-v" in the built-in help, so
changed the built-in help)
