NAME
     autopush - configure lists of automatically pushed STREAMS modules

SYNOPSIS
     autopush -f file
     autopush -r -M major -m minor
     autopush -g -M major -m minor

DESCRIPTION
     autopush allows you to configure the list of modules to be automatically
     pushed onto the stream when a device is opened.  It can also be used to
     remove a previous setting or get information on a setting.

     The following options apply to autopush:

     -f file   This option sets up the autopush configuration for each driver
               according to the information stored in the specified file.  An
               autopush file consists of lines of at least four fields each,
               where the fields are separated by a space as shown below:


                    maj  min  last_min  mod1 mod2 ... modn

               The first three fields are integers that specify the major
               device number, minor device number, and last minor device
               number.  The fields following represent the names of modules.
               If min is -1, then all minor devices of a major driver
               specified by maj are configured and the value for last_min is
               ignored.  If last_min is 0, then only a single minor device is
               configured.  To configure a range of minor devices for a
               particular major, min must be less than last_min.

               The last fields of a line in the autopush file represent the
               list of module names where each is separated by a space.  The
               maximum number of modules that can be automatically pushed on a
               stream is defined to be eight.  The modules are pushed in the
               order they are specified.  Comment lines start with a # sign.

     -r        Remove the previous configuration setting of the particular
               major and minor device number specified with the -M and -m
               options respectively.  If the values of major and minor
               correspond to a setting of a range of minor devices where minor
               matches the first minor device number in the range, the
               configuration would be removed for the entire range.

     -g        Get the current configuration setting of a particular major and
               minor device number specified with the -M and -m options,
               respectively.  It also returns the starting minor device number
               if the request corresponds to a setting of a range (as
               described with the -f option).
