used to determine which processes are the browser processes.

=item * B<exec_pat> => I<re_from_str>

Filter processes using regex against their exec.

If one of the C<*-pat> options are specified, then instead of the default
heuristic rules to find the browser processes, these C<*-pat> options are solely
used to determine which processes are the browser processes.

=item * B<fname_pat> => I<re_from_str>

Filter processes using regex against their fname.

If one of the C<*-pat> options are specified, then instead of the default
heuristic rules to find the browser processes, these C<*-pat> options are solely
used to determine which processes are the browser processes.

=item * B<pid_pat> => I<re_from_str>

Filter processes using regex against their pid.

If one of the C<*-pat> options are specified, then instead of the default
heuristic rules to find the browser processes, these C<*-pat> options are solely
used to determine which processes are the browser processes.

=item * B<quiet> => I<true>

(No description)

=item * B<users> => I<array[unix::uid::exists]>

Kill browser processes that belong to certain user(s) only.

Returns an enveloped result (an array).

First element ($status_code) is an integer containing HTTP-like status code
(200 means OK, 4xx caller error, 5xx function error). Second element
($reason) is a string containing error message, or something like "OK" if status is
200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth
element (%result_meta) is called result metadata and is optional, a hash
that contains extra information, much like how HTTP response headers provide additional metadata.

Return value:  (any)



=head2 chrome_is_running

Usage:

 chrome_is_running(%args) -> [$status_code, $reason, $payload, \%result_meta]

Check whether Chrome is running.

Chrome is defined as running if there are some Chrome processes that are I<not>
in 'stop' state. In other words, if Chrome has been started but is currently
paused, we do not say that it's running. If you want to check if Chrome process
exists, you can use C<ps_chrome>.

This function is not exported.
