    If PID is omitted current process PID (os.getpid()) is used.
    Raise NoSuchProcess if PID does not exist.

    Note that most of the methods of this class do not make sure that
    the PID of the process being queried has been reused. That means
    that you may end up retrieving information for another process.

    The only exceptions for which process identity is pre-emptively
    checked and guaranteed are:

     - parent()
     - children()
     - nice() (set)
     - ionice() (set)
     - rlimit() (set)
     - cpu_affinity (set)
     - suspend()
     - resume()
     - send_signal()
     - terminate()
     - kill()

    To prevent this problem for all other methods you can use
    is_running() before querying the process.

Process._initcCs.tr|jjdd�|_|j|jfS|j|��fS)aReturn a (pid, uid) tuple which is supposed to identify a
        Process instance univocally over time. The PID alone is not
        enough, as it can be assigned to a new process after this one
        terminates, so we add process creation time to the mix. We need
        this in order to prevent killing the wrong process later on.
        This is also known as PID reuse or PID recycling problem.

        The reliability of this strategy mostly depends on
        create_time() precision, which is 0.01 secs on Linux. The
        assumption is that, after a process terminates, the kernel
        won't reuse the same PID after such a short period of time
        (0.01 secs). Technically this is inherently racy, but
        practically it should be good enough.

        retrieval of multiple process information at the same time.

        Internally different process info (e.g. name, ppid, uids,
        gids, ...) may be fetched by using the same routine, but
        only one information is returned and the others are discarded.
        When using this context manager the internal routine is
        executed once (in the example below on name()) and the
        other info are cached.

        The cache is cleared when exiting the context manager block.
        The advice is to use this every time you retrieve more than
        one information about the process. If you're lucky, you'll
        get a hell of a speedup.

        >>> import psutil
        >>> p = psutil.Process()
        >>> with p.oneshot():
        ...     p.name()  # collect multiple info
        ...     p.cpu_times()  # return cached value
        ...     p.cpu_percent()  # return cached value
        ...     p.create_time()  # return cached value

aReturn a float representing the current process CPU
        utilization as a percentage.

        When *interval* is 0.0 or None (default) compares process times
        to system CPU times elapsed since last call, returning
        immediately (non-blocking). That means that the first time
        this is called it will return a meaningful 0.0 value.

        When *interval* is > 0.0 compares process times to system CPU
        times elapsed before and after the interval (blocking).

        In this case is recommended for accuracy that this function
        be called with at least 0.1 seconds between calls.

        A value > 100.0 can be returned in case of processes running
        multiple threads on different CPU cores.

        The returned value is explicitly NOT split evenly between
        all available logical CPUs. This means that a busy loop process
        running on a system with 2 logical CPUs will be reported as
        having 100% CPU utilization instead of 50%.

        Examples:

          >>> import psutil
          >>> p = psutil.Process(os.getpid())
          >>> # blocking
          >>> p.cpu_percent(interval=1)

          >>> # non-blocking (percentage since last call)

        plus, on some platform (Linux, macOS, Windows), also provides
        additional metrics (USS, PSS and swap).
        The additional metrics provide a better representation of actual
        process memory usage.

        Namely USS is the memory which is unique to a process and which
        would be freed if the process was terminated right now.

        It does so by passing through the whole process address.
        As such it usually requires higher user privileges than
        memory_info() and is considerably slower.

    For the following methods which are common to both classes, psutil

    * send_signal()
    * terminate()
    * kill()

    This is done in order to avoid killing another process in case its
    PID has been reused, fixing BPO-6973.

    Every new Process instance is only created once and then cached
    into an internal table which is updated every time this is used.
    Cache can optionally be cleared via `process_iter.clear_cache()`.

    The sorting order in which processes are yielded is based on
    their PIDs.

    *attrs* and *ad_value* have the same meaning as in
    Process.as_dict(). If *attrs* is specified as_dict() is called

    Return a (gone, alive) tuple indicating which processes
    are gone and which ones are still alive.

    The gone ones will have a new *returncode* attribute indicating
    process exit status (may be None).

    *callback* is a function which gets called every time a process
    terminates (a Process instance is passed as callback argument).

    Function will return as soon as all processes terminate or when
    *timeout* occurs.
    Differently from Process.wait() it will not raise TimeoutExpired if
    *timeout* occurs.

    Typical use case is:

     - send SIGTERM to a list of processes
     - give them some time to terminate
     - send SIGKILL to those ones which are still alive

    Example:

    >>> def on_terminate(proc):

    When *interval* is 0.0 or None compares system CPU times elapsed
    since last call or module import, returning immediately (non

    return a meaningless 0.0 value which you should ignore.
    In this case is recommended for accuracy that this function be

a�Same as cpu_percent() but provides utilization percentages
    for each specific CPU time as is returned by cpu_times().
    For instance, on Linux we'll get:

getloadavgcCst��}|ja|S)a�Return statistics about system memory usage as a namedtuple
    including the following fields, expressed in bytes:

     - total:
       total physical memory available.

     - available:
       the memory that can be given instantly to processes without the
       system going into swap.
       This is calculated by summing different memory values depending
       on the platform and it is supposed to be used to monitor actual
       memory usage in a cross platform fashion.

     - percent:
       the percentage usage calculated as (total - available) / total * 100

     - used:
        memory used, calculated differently depending on the platform and
        designed for informational purposes only:
        macOS: active + wired
        BSD: active + wired + cached
        Linux: total - free

     - free:
       memory not being used at all (zeroed) that is readily available;
       note that this doesn't reflect the actual memory available
       (use 'available' instead)

    Platform-specific fields:

     - active (UNIX):
       memory currently in use or very recently used, and so it is in RAM.

     - inactive (UNIX):
       memory that is marked as not used.

     - buffers (BSD, Linux):
       cache for things like file system metadata.

     - cached (BSD, macOS):
       cache for various things.

     - wired (macOS, BSD):
       memory that is marked to always stay in RAM. It is never moved to disk.

     - shared (BSD):
       memory that may be simultaneously accessed by multiple processes.

    The sum of 'used' and 'available' does not necessarily equal total.
    On Windows 'available' and 'free' are the same.
    )rwrTrTrSr�rlrlrmrT�s5rTcCr�)a�Return system swap memory statistics as a namedtuple including
    the following fields:

     - total:   total swap memory in bytes
     - used:    used swap memory in bytes
     - free:    free swap memory in bytes
     - percent: the percentage usage
     - sin:     no. of bytes the system has swapped in from disk (cumulative)
     - sout:    no. of bytes the system has swapped out from disk (cumulative)

    'sin' and 'sout' on Windows are meaningless and always set to 0.

    (device, mountpoint, fstype, opts) namedtuple.
    'opts' field is a raw string separated by commas indicating mount
    options which may vary depending on the platform.

    all others.

     - write_count: number of writes
     - read_bytes:  number of bytes read
     - write_bytes: number of bytes written
     - read_time:   time spent reading from disk (in ms)
     - write_time:  time spent writing to disk (in ms)

    Platform specific:

     - busy_time: (Linux, FreeBSD) time spent doing actual I/Os (in ms)
     - read_merged_count (Linux): number of merged reads
     - write_merged_count (Linux): number of merged writes

    If *perdisk* is True return the same information for every
    physical disk installed on the system as a dictionary
    with partition names as the keys and the namedtuple
    described above as the values.

    If *nowrap* is True it detects and adjust the numbers which overflow
    and wrap (restart from 0) and add "old value" to "new value" so that
    the returned numbers will always be increasing or remain the same,
    but never decrease.
    "disk_io_counters.cache_clear()" can be used to invalidate the
    cache.

    On recent Windows versions 'diskperf -y' command may need to be
    executed first otherwise this function won't find any disk.

     - dropout:      total number of outgoing packets which were dropped
                     (always 0 on macOS and BSD)

    If *pernic* is True return the same information for every
    network interface installed on the system as a dictionary
    with network interface names as the keys and the namedtuple
    described above as the values.

    If *nowrap* is True it detects and adjust the numbers which overflow

     - family: can be either socket.AF_INET, socket.AF_INET6 or
               psutil.AF_LINK, which refers to a MAC address.
     - address: is the primary address and it is always set.
     - netmask: and 'broadcast' and 'ptp' may be None.
     - ptp: stands for "point to point" and references the
