INPUT_GET_NEW_MINOR(9) Input Subsystem INPUT_GET_NEW_MINOR(9)NAME
input_get_new_minor - allocates a new input minor number
SYNOPSIS
int input_get_new_minor(int legacy_base, unsigned int legacy_num, bool allow_dynamic);
ARGUMENTS
legacy_base
beginning or the legacy range to be searched
legacy_num
size of legacy range
allow_dynamic
whether we can also take ID from the dynamic range
DESCRIPTION
This function allocates a new device minor for from input major namespace. Caller can request legacy minor by specifying legacy_base and
legacy_num parameters and whether ID can be allocated from dynamic range if there are no free IDs in legacy range.

autopush - manage system database of automatically pushed STREAMS modules
SYNOPSIS
file
major minor
major minor
DESCRIPTION
manages the system database that is used for automatic configuration of STREAMS devices. The command is used in three different ways as
dictated by the and command-line options described below.
Options
recognizes the following command-line options and arguments:
Using the configuration information contained in
file, load the system database with the names of the STREAMS devices and a list of modules to use for each device.
When a device is subsequently opened, the HP-UX STREAMS subsystem pushes the modules onto the stream for the device.
If appears as a file argument, uses the standard input.
file must contain one or more lines of at least four fields separated by a space as shown below:
major minor lastminor module1 module2 ... moduleN
The first field major can be either an integer or a device name. The device name is the name for the device used in
the master file. The next two fields are integers. If minor is set to -1, then all minor devices for the specified
major are configured and lastminor is ignored. If lastminor is 0, then only a single minor device is configured. To
configure a range of minor devices for a major device, minor must be less then lastminor. The remaining field(s)
list one or more module names. Each module is pushed in the order specified. A maximum of eight modules can be
pushed. Any text after a # character in file is treated as a comment for that line only.
This option is also used to restore device configuration information previously removed by However, when used in such
a manner, the entire database is restored, not just the information that was previously removed.
Display current configuration information from the system database for the
STREAMS device specified by the major device number (or device name for the device from the master file) and minor
number.
If a range of minors has been previously configured then returns the configuration information for the first minor in
the range, in addition to other information.
Remove configuration information from the system database for the
STREAMS device specified by the major device number (or device name for the device from the master file and minor
number. Removal is performed on the database only, not on the original configuration file. Therefore, the original
configuration can be restored by using the file option. To permanently exclude a STREAMS device from the database,
its information must be removed from the configuration file.
If minor matches the first minor of a previously configured range then removes the configuration information for the
entire configured range.
EXAMPLES
If the file contains:
Then will cause and to be pushed whenever major device is opened, and and to be pushed for the first six opens of device
This next example lists information about the stream for major device and its minor device
