       astribank_is_starting - Mark / check is a Xorcom Astribank (xpp) is starting


       astribank_is_starting [-d] [-v] [-t timeout] <-a|-r|-w>

       astribank_is_starting [-d] [-v]

       astribank_is_starting -h


       astribank_is_starting  is  an internal tool used by various xpp scripts to mark that there
       may be an Astribank device currently initializing, and to check for that mark.

       Technically the mark is a SysV semaphore.


              Add.  Set the mark. Should return 0 unless there's an error.

              Remove.  Reset the mark. Should return 0 unless there's an error.

              Timeout.  Set the timeout value for the -w option. Default is 60 seconds.

              Wait.  Wait for mark to be reset. Should return 0 unless there's an error.

       Without -a or -r: return 0 if the mark has been set, or a non-zero value otherwise.

              Print debug information to stderr.

              Verbose execution.

              Displays usage message.


              If set, the  astribank  should  appear  there  with  the  ID  11211168  (0xAB11A0).
              Naturally  the  ID  (or  rather, the usage of a semaphore in the first place) is an
              implementation detail that may change.


       astribank_is_starting is used to  mark  the  fact  that  an  Astribank  may  be  currently
       reenumerating  (technically:  distonnecting  and  connecting  as  a  new USB device) after
       loading    the    firmware.    Thus    the    script    that    loads     the     firmware
       (/usr/share/dahdi/xpp_fxloader) uses this utility to set the mark.

       The  mark  is reset by /usr/share/dahdi/waitfor_xpds , which is typically run by the DAHDI
       init script and waits for all Astribanks to finish loading.

       Q: Why do you use a semaphore?

       A: because, unlike the filesystem, it is writable at any given time.


       Option ordering matter. The -v and -d options should preceed the actions (-a, -r and  -w).
       The -ttimeout option should preceed the -w option.
