The lock file is a normal file named by the attribute `path`. A lock's PID file contains a single line of text, containing the process ID (PID) of the process that acquired the lock. >>> lock = PIDLockFile('somefile') >>> lock = PIDLockFile('somefile') FNc �L � t j | |d|� � | j | _ d S )NF)r �__init__�path� unique_name)�selfr �threaded�timeouts �K/opt/imunify360/venv/lib64/python3.11/site-packages/lockfile/pidlockfile.pyr zPIDLockFile.__init__$ s+ � � ��$��e�W�5�5�5� �9����� c �* � t | j � � S )z- Get the PID from the lock file. )�read_pid_from_pidfiler �r s r �read_pidzPIDLockFile.read_pid* s � � %�T�Y�/�/�/r c �J � t j � | j � � S )zv Test if the lock is currently held.
