utils::Task Class Reference

List of all members.

Detailed Description

Manage asynchronous subprocess tasks.
   This differs from the 'subproc' package!
    - 'subproc' connects to the subprocess via pipes
    - 'task' lets the subprocess run autonomously.
   After starting the task, we can just:
    - ask whether it is finished yet
    - wait until it is finished
    - perform an 'idle' task (e.g. Tkinter's mainloop) while waiting for
      subprocess termination
    - kill the subprocess with a specific signal
    - ask for the exit code.
    - 'subproc' is a sophisticated os.popen()
    - 'task' is a sophisticated os.system()
   Another difference of task with 'subproc':
    - If the Task() object is deleted, before the subprocess status
      was retrieved, the child process will stay.
      It will never be waited for (i.e., the process will turn into
      a zombie. Not a good idea in general).
