getdevicerange(3TSOL)Trusted Extensions Library Functionsgetdevicerange(3TSOL)NAMEgetdevicerange - get the label range of a device
SYNOPSIS
cc [flag...] 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-allo‐
catable 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.
