-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Under Windows, programmatically retrieving the parent process ID of the openvpn instance which called a script is practically impossible. The only sensible way, currently available, is to write a PID file.
This patch adds a single integer variable, named daemon_pid, to the script environment. The value of which is set to the openvpn process ID that called the script. Providing this variable via the running openvpn process is more secure, faster and far less prone to user-error than using a PID file.
