Pid::File::Flock - PID file operations
You can use module generic way:
use Pid::File::Flock; ... Pid::File::Flock->new; Pid::File::Flock->new('file'); Pid::File::Flock->new(debug=>1, dir=>'/tmp');
or in simplified form:
use Pid::File::Flock qw(:auto); use Pid::File::Flock qw(:auto :raise); use Pid::File::Flock qw(:auto path=file); use Pid::File::Flock qw(:auto :debug dir=/tmp);
you can mix both too:
use Pid::File::Flock qw(:debug dir=/tmp); ... Pid::File::Flock->new(ext=>'.old');
You can provide 'flag' options ('debug','quiet') like an import tag:
use Pid::File::Flock qw(:debug :quiet)
Valued options can be specified with key=value form:
use Pid::File::Flock qw(dir=/tmp ext=.old)
Pseudo tag ':auto' create lock object implicitly.
Optional argument, if provided options 'dir','name' and 'ext' will be silently ignored.
Base directory for pid file (by default File::Spec::tmpdir called).
Name for pid file (by default like a script self).
Extension for pid file ('.pid' by default).
croak instead of simple
exit. Usable from caller eval block to handle unsuccessful locking attempts.
Switch debug mode on (some information via STDERR).
Switch quiet mode on (don't warn about staled pid files).
Don't try to remove pid file during destruction. Become for using in forking applications.
You haven't call these methods directly.
Process 'fake' import list.
Acquiring lock, called by
Attempting acquire lock with additional checks.
Unlink pid file, handle will be closed a bit later, during object destructing.
Lock object destructor.
Undefine module lexical variable to force DESTROY invoking.

Module works with advisory files locking which is not implemented on win32 platform.
