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 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.
