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.
