uniq_pid_undertaker

determine whether a process has exited

Synopsis

uniq_pid_undertaker [- -block] [- -file file] [- -precision seconds]

Description

uniq_pid_undertaker can examine an artifact file created by uniq_pid_midwife and determine whether the program started by the midwife has exited.

Options

- -block

If the process has not exited, block until it does.

- -file file

The name of the uniq_pid_midwife created artifact file. Defaults to pid.file.

- -precision seconds

Uses seconds as the precision range within which the operating system will provide a process's birthday. Defaults to an operating system specific value. Only use this option if the same seconds value was provided to uniq_pid_midwife.

Exit Status

uniq_pid_undertaker will exit with a status of 0 (zero) if the monitored process has exited, with a status of 1 (one) if the monitored process has definitely not exited, with a status of 2 if it is uncertain whether the process has exited (this is generally due to a failure by the uniq_pid_midwife), or with any other value for program failure.
