  25 # This is the audio_clean program.
  26 #
  27 # Following is the syntax for calling the script:
  28 #       scriptname [-s|-f|-i|-I] devicename [-A|-D] [username] [zonename]
  29 #           [zonepath]
  30 #
  31 # $1:   -s for standard cleanup by a user
  32 #       -f for forced cleanup by an administrator
  33 #       -i for boot-time initialization (when the system is booted with -r)
  34 #       -I to suppress error/warning messages; the script is run in the '-i'
  35 #       mode
  36 #
  37 # $2:   devicename - device to be allocated/deallocated, e.g., sr0
  38 #
  39 # $3:   -A if cleanup is for allocation, or -D if cleanup is for deallocation.
  40 #
  41 # $4:   username - run the script as this user, rather than as the caller.
  42 #
  43 # $5:   zonename - zone in which device to be allocated/deallocated
  44 #
  45 # $6:   zonepath - root path of zonename
  46 #
  47 # Unless the clean script is being called for boot-time
  48 # initialization, it may communicate with the user via stdin and
  49 # stdout.  To communicate with the user via CDE dialogs, create a
  50 # script or link with the same name, but with ".windowing" appended.
  51 # For example, if the clean script specified in device_allocate is
  52 # /etc/security/xyz_clean, that script must use stdin/stdout.  If a
  53 # script named /etc/security/xyz_clean.windowing exists, it must use
  54 # dialogs.  To present dialogs to the user, the dtksh script
  55 # /etc/security/lib/wdwmsg may be used.
  56 #
  57 # This particular script, audio_clean, will work using stdin/stdout, or
  58 # using dialogs.  A symbolic link audio_clean.windowing points to
  59 # audio_clean.
