autopush(1M) System Administration Commands autopush(1M)NAMEautopush - configures lists of automatically pushed STREAMS modules
SYNOPSISautopush-f filename
autopush-g -M major -m minor
autopush-r -M major -m minor
DESCRIPTION
The autopush command configures 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.
OPTIONS
The following options are supported:
-f filename Sets up the autopush configuration for each driver
according to the information stored in filename. An
autopush file consists of lines of four or more fields,
separated by spaces as shown below:
major minor last-minor module1 module2 ... module8
The first field is a string that specifies the major
device name, as listed in the /kernel/drv directory.
The next two fields are integers that specify the minor
device number and last-minor device number. The fields
following represent the names of modules. If minor is
−1, then all minor devices of a major driver specified
by major are configured, and the value for last-minor
is ignored. If last-minor is 0, then only a single
minor device is configured. To configure a range of
minor devices for a particular major, minor must be
less than last-minor.
The remaining fields list the names of modules to be
automatically pushed onto the stream when opened, along
with the position of an optional anchor. The maximum
number of modules that can be pushed is eight. The mod‐
ules are pushed in the order they are specified. The
optional special character sequence [anchor] indicates
that a STREAMS anchor should be placed on the stream at
the module previously specified in the list; it is an
error to specify more than one anchor or to have an
anchor first in the list.
A nonzero exit status indicates that one or more of the
lines in the specified file failed to complete success‐
fully.
-g Gets the current configuration setting of a particular
major and minor device number specified with the -M and
-m options respectively and displays the autopush mod‐
ules associated with it. It will also return the start‐
ing minor device number if the request corresponds to a
setting of a range (as described with the -f option).
-m minor Specifies the minor device number.
-M major Specifies the major device number.
-r Removes the previous configuration setting of the par‐
ticular major and minor device number specified with
the -M and -m options respectively. If the values of
major and minor correspond to a previously established
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.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
non-zero An error occurred.
EXAMPLES
Example 1: Using the autopush command.
The following example gets the current configuration settings for the
major and minor device numbers as indicated and displays the autopush
modules associated with them for the character-special device
