- get the label range of a user
cc [flags...] file... -ltsol [library...]
#include <tsol/label.h> m_range_t *getuserrange(const char *username);
The getuserrange() function returns the label range of username. The lower bound in the range is used as the initial workspace label when a user logs into a multilevel desktop. The upper bound, or clearance, is used as an upper limit to the available labels that a user can assign to labeled workspaces.
The getuserrange() function returns NULL if the memory allocation fails. Otherwise, the function returns a structure which must be freed by the caller, as follows:
m_range_t *range; ... m_label_free(range->lower_bound); m_label_free(range->upper_bound); free(range);
The getuserrange() function will fail if:
The physical limits of the system are exceeded by size bytes of memory which cannot be allocated.
See attributes(5) for descriptions of the following attributes:
The getuserrange() function is Committed for systems that implement the Defense Intelligence Agency (DIA) MAC policy of label_encodings(4). Other policies might exist in a future release of Trusted Extensions that might make obsolete or supplement label_encodings.
The functionality described on this manual page is available only if the system is configured with Trusted Extensions.
