procset(4)procset(4)NAME
procset.h - Send a signal to one or more processes
SYNOPSIS
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
The contents of the <procset.h> structure define a set of target pro‐
cesses based on logical operations performed on the two sets of poten‐
tial target processes indicated by the two pairs of id + type parame‐
ters, which designate "left" and "right" groups of processes. The log‐
ical 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 pro‐
cesses, 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.
