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.

NAME

       blcompare, blequal, bldominates, blstrictdom, blinrange - compare binary labels

SYNOPSIS

       cc [flag...] file... -ltsol [library...]
       #include <tsol/label.h>

       int blequal(const m_label_t *label1, const m_label_t *label2);

       int bldominates(const m_label_t *label1, const m_label_t *label2);

       int blstrictdom(const m_label_t *label1, const m_label_t *label2);

       int blinrange(const m_label_t *label, const brange_t *range);

DESCRIPTION

       These functions compare binary labels for meeting a particular condition.

       The blequal() function compares two labels for equality.

       The bldominates()  function compares label label1 for dominance over label label2.

       The blstrictdom()  function compares label label1 for strict dominance over label label2.

       The blinrange()	function compares label label for dominance over range->lower_bound and range->upper_bound for dominance over level label.

RETURN VALUES

       These functions return non-zero if their respective conditions are met, otherwise zero is returned.
