       procset.h - Send a signal to one or more processes

SYNOPSIS    [Toc]    [Back]

       typedef struct procset {
               idop_t  *p_op;
               idtype_t p_lidtype;
               id_t     p_lid;
               idtype_t p_ridtype;
               id_t     p_rid; } procset_t;

DESCRIPTION    [Toc]    [Back]

       The  contents of the <procset.h> structure define a set of
       target processes based on logical operations performed  on
       the  two  sets  of potential target processes indicated by
       the two pairs of id +  type  parameters,  which  designate
       "left" and "right" groups of processes.  The logical operations
 supported are the union, intersection,  difference,
       and exclusive OR of the left and right groups.

       The  p_lid  and p_lidtype members define one set of potential
 target processes, the  "left"  set.   The  p_rid  and
       p_ridtype members define the "right" set of potential target
 processes.  These parameters work together  to  select
       the target process or processes.

       The value of p_op is used to combine these two groups into
       the final group of actual target processes: Specifies that
       the  target  group  of  processes consist of the remaining
       processes in the left set that are not common to the right
       set.   Specifies  that  the target group consists of those
       processes that are in both sets.  Specifies that the  target
  group  consists of those processes that are in either
       set, or in both sets.  Specifies  that  the  target  group
       consists  of  those  processes that are in either set, but
       not in both sets.
