Name
set_union
Synopsis
int set_union(Set *setu, const Set *set1, const Set *set2);
Return Value
0 if computing the union is successful, or -1 otherwise.
Description
Builds a set that is the union of
set1 and
set2. Upon return,
setu contains the union. Because
setu points to data in
set1 and
set2, the data in
set1 and
set2 must remain valid until
setu is destroyed with
set_destroy.
Complexity
O (mn), where
m and n are the number
of members in set1 and
set2, respectively.
