# This is the audio_clean program.
#
# Following is the syntax for calling the script:
#	scriptname [-s|-f|-i|-I] devicename [-A|-D] [username] [zonename]
#           [zonepath]
#
# $1:	-s for standard cleanup by a user
#	-f for forced cleanup by an administrator
#	-i for boot-time initialization (when the system is booted with -r)
#	-I to suppress error/warning messages; the script is run in the '-i'
#	mode
#
# $2:	devicename - device to be allocated/deallocated, e.g., sr0
#
# $3:	-A if cleanup is for allocation, or -D if cleanup is for deallocation.
#
# $4:	username - run the script as this user, rather than as the caller.
#
# $5:	zonename - zone in which device to be allocated/deallocated
#
# $6:	zonepath - root path of zonename
#
# Unless the clean script is being called for boot-time
# initialization, it may communicate with the user via stdin and
# stdout.  To communicate with the user via CDE dialogs, create a
# script or link with the same name, but with ".windowing" appended.
# For example, if the clean script specified in device_allocate is
# /etc/security/xyz_clean, that script must use stdin/stdout.  If a
# script named /etc/security/xyz_clean.windowing exists, it must use
# dialogs.  To present dialogs to the user, the dtksh script
# /etc/security/lib/wdwmsg may be used.
#
# This particular script, audio_clean, will work using stdin/stdout, or
# using dialogs.  A symbolic link audio_clean.windowing points to
# audio_clean.
