The priocntlset(2) function changes scheduler parameters of a set of processes, like priocntl(2). priocntlset(2) has the same command set as priocntl(2). The cmd and arg input arguments are the same. But while priocntl(2) applies to a set of processes specified by a single idtype/id pair, priocntlset(2) applies to a set of processes that results from a logical combination of two idtype/id pairs. Again, refer to the manual page for details.
