set_intersect

Gets the intersection of two sets.

Syntax

bool set_intersect(Set* left, Set* right, Set* result);
Name Type Description
left Set* A pointer to the left set.
right Set* A pointer to the right set.
result Set* A pointer to the result set.

Returns: true if none of the sets were NULL, false otherwise.

Example

SET_DEFINE_H(StringSet, str_set, char*)
SET_DEFINE_C(StringSet, str_set, char*, gds_fnv32, strcmp)

StringSet* left = str_set_create();
StringSet* right = str_set_create();
StringSet* result = str_set_create();

str_set_add(left, "moo");
str_set_add(left, "nyan");
str_set_add(right, "caw");
str_set_add(right, "nyan");

str_set_intersect(left, right, result);

printf("%d\n", str_set_contains(result, "moo"));
printf("%d\n", str_set_contains(result, "caw"));
printf("%d\n", str_set_contains(result, "nyan"));

// Output:
// 0
