   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
         This command allows one 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    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  lastmin  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    This option removes 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    This option gets the current configuration setting of a
               particular major and minor device number specified with the -M
               and -m options respectively. It will also return the starting
               minor device number if the request corresponds to a setting of
               a range (as described with the -f option).
