cf_map_get

Category: map
GitHub: cute_map.h

Fetches the item that k maps to.

#define cf_map_get(m, k) map_get(m, k)
Parameters Description
m The map. Can be NULL. Must be declared with CF_MAP(T).
k The key for lookups. Keys are always typecast to uint64_t.

Return Value

Returns the item by value. If the key doesn't exist, returns a zero'd item.

Code Example

Set and get a few elements from a map.

CF_MAP(int) table = NULL;
map_set(table, 0, 5);
map_set(table, 1, 12);
CF_ASSERT(map_get(table, 0) == 5);
CF_ASSERT(map_get(table, 1) == 12);
map_free(table);

Remarks

Items are returned by value, not pointer. If you want a pointer (to check for NULL when the item doesn't exist), use map_get_ptr. You can also call map_has to check existence.
