SYNOPSIS
cc [

file...
-lbsm -ltsol [
library...]
#include <tsol/label.h>
blrange_t *getdevicerange(
const char *device);
DESCRIPTION
The
getdevicerange() function returns the label range of a user-
allocatable device.
If the label range is not specified for
device,
getdevicerange() returns the default values of
ADMIN_LOW for the lower bound and
ADMIN_HIGH for the upper bound of
device.
From the command line,
list_devices(1) can be used to see the label
range of
device.
RETURN VALUES
The
getdevicerange() function returns
NULL on failure and sets
errno.
On successful completion, it returns a pointer to a
blrange_t structure which must be freed by the caller, as follows:
blrange_t *range;
...
m_label_free(range->lower_bound);
m_label_free(range->upper_bound);
free(range);
ERRORS
The
getdevicerange() function will fail if:
EAGAIN There is not enough memory available to allocate the
required bytes. The application could try later.
ENOMEM The physical limits of the system are exceeded by size
bytes of memory which cannot be allocated.
ENOTSUP Invalid upper or lower bound for device.
