This example shows three ways to create an attribute mask in addition to instantiating a mask structure and or'ing the desired enumerated fields.
#include <tsix/t6attrs.h>
#include <tsol/label.h>
main()
{
t6mask_t suppmask, allocmask, presentmask;
t6mask_t getmask, recvmask;
t6attr_t attrs, getattrs, recvattrs;
recvmask = T6M_ALL_ATTRS; recvattrs = t6alloc_blk(recvmask);
getmask = T6M_CLEARANCE; getattrs = t6alloc_blk(getmask);
/* Get mask of system-supported attributes */
suppmask = t6supported_attrs();
/* Get mask of attributes for which space is */
/* allocated in rcvattrs (T6M_ALL_ATTRS)*/
allocmask = t6allocated_attrs(rcvattrs);
/* Get mask of attributes present in getattrs */
presentmask = t6present_attrs(getattrs);
}
