NAME

allocate - device allocation

SYNOPSIS

allocate [-s] [-w] [-F] [-U uname] [-z zonename] device


allocate [-s] [-w] [-F] [-U uname] [-z zonename] -g dev-type

DESCRIPTION

The allocate utility manages the ownership of devices through its
allocation mechanism. It ensures that each device is used by only one
qualified user at a time.


The device argument specifies the device to be manipulated. To
preserve the integrity of the device's owner, the allocate operation
is executed on all the device special files associated with that
device.


The default allocate operation allocates the device special files
associated with device to the uid of the current process.


Only authorized users may allocate a device. The required
authorizations are specified in device_allocate(5).


When the system is configured with Trusted Extensions, allocate runs
the clean program for the device before it grants access to the
caller to that device. For devices with removable media that have a
mountable file system, allocate mounts the media if the caller
chooses.

OPTIONS

The following options are supported:

-F device
Force allocates either free or pre-allocated
devices. This option is often used with the -U
option to allocate/reallocate devices to a specific
user. Only those users that have
solaris.device.revoke authorization are allowed to
use this option.


-g dev-type
Allocates devices with a device-type matching
dev-type. The dev-type argument specifies the
device type to be operated on.


-s
Silent. Suppresses any diagnostic output.


-U uname
Uses the user ID uname instead of the user ID of
the current process when performing the allocate
operation. Only a user with the
solaris.device.revoke authorization is permitted to
use this option.


The following options are supported with Trusted Extensions:

-w
Runs the device cleaning program in a windowing
environment. If a windowing version of the program
exists, it is used. Otherwise, the standard version is
run in a terminal window.


-z zonename
Allocates device to the zone specified by zonename.

OPERANDS

The following operands are supported:

device
Specifies the name of the device to be allocated.

EXIT STATUS

The following exit values are returned:

0
Successful completion.


20
No entry for the specified device.


other value
An error occurred.
