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

       m_label, m_label_alloc, m_label_dup, m_label_free - m_label functions

SYNOPSIS

       cc [flag...] file... -ltsol [library...]

       #include <tsol/label.h>

       m_label_t *m_label_alloc(const m_label_type_t label_type);

       int m_label_dup(m_label_t **dst, const m_label_t *src);

       void m_label_free(m_label_t *label);

DESCRIPTION

       The m_label_alloc() function allocates resources for a new label. The label_type argument defines the type for a newly allocated label. The
       label type can be:

       MAC_LABEL     A Mandatory Access Control (MAC) label.

       USER_CLEAR    A user clearance.

       The m_label_dup() function allocates resources for a new dst label. The function returns a pointer to the  allocated  label,  which  is	an
       exact copy of the src label. The caller is responsible for freeing the allocated resources by calling m_label_free().

       The m_label_free() function frees resources that are associated with the previously allocated label.

RETURN VALUES

       Upon successful completion, the m_label_alloc() function returns a pointer to the newly allocated label. Otherwise, m_label_alloc() returns
       NULL and errno is set to indicate the error.

       Upon successful completion, the m_label_dup() function returns 0. Otherwise, -1 is returned and errno is set to indicate the error.

ERRORS

       The m_label_alloc() function will fail if:

       EINVAL	 Invalid parameter.

       ENOMEM	 The physical limits of the system are exceeded by size bytes of memory which cannot be allocated.
