Unix::PID::Tiny - Subset of Unix::PID functionality with smaller memory footprint
This document describes Unix::PID::Tiny version 0.92.
use Unix::PID::Tiny; my $pid = Unix::PID::Tiny->new(); print Dumper( $pid->pid_info_hash( $misc_pid ) ); if ($pid->is_pid_running($misc_pid)) { $pid->kill( $misc_pid ) or die "Could not stop $misc_pid"; }
Like Unix::PID but supplies only a few key functions.
See Unix::PID's new(). The following options can be provided in the optional HASH, $args_hr, to enable certain extensions:
When a true value is provided, PID files created with pid_file() will remain open.
When a true value is provided, this option will cause is_pidfile_running() to traverse /proc/$pid/fd to ensure a current file descriptor is held by a given process for the specified PID file.
/proc/$pid/fd
This option is only useful when keep_open is also enabled, or when a pid file supplied by an external entity is passed to is_pidfile_running(). In other words, if this option is set when is_pidfile_running() is called, that function will always return false unless an open file descriptor is held for the same PID file by the process of that same PID.
See Unix::PID's kill()
See Unix::PID's pid_info_hash()
See Unix::PID's is_pid_running(). The optional argument $since may be provided, which will cause this function to not return true if the mtime of $pid_file is earlier than the value provided in $since.
See Unix::PID's get_pid_from_pidfile()
See Unix::PID's is_pidfile_running()
See Unix::PID's pid_file()
The "retry" configuration can also be hash ref w/ the optional keys:
This number corresponds to the the array ref version’s “first item”. Defaults to 3.
This array ref corresponds to the the array ref version’s “additional arguments”. Defaults to [1,2].
See Unix::PID's pid_file_no_unlink()
Alias of pid_file_no_unlink(). Some folks like this name better.
See Unix::PID's _raw_ps()
If $self->{'ps_path'} is ever set to anything invalid at any point it is simply not used and 'ps' by itself will be used.
See Unix::PID's DIAGNOSTICS
