NAME
       getdevicerange - 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-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  struc-
       ture 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.
