cf_map_keys¶
Category: map
GitHub: cute_map.h
Get a pointer to the array of keys.
| Parameters | Description |
|---|---|
m |
The map. Can be NULL. Must be declared with CF_MAP(T). |
Return Value¶
Returns uint64_t* pointing to the keys array, or NULL if map is empty.
Code Example¶
Loop over all {key, item} pairs.
CF_MAP(CF_V2) table = my_table();
uint64_t* keys = map_keys(table);
for (int i = 0; i < map_size(table); ++i) {
uint64_t key = keys[i];
CF_V2 item = table[i];
// ...
}
Remarks¶
The keys array is parallel to the items array. Use with map_size for iteration bounds.
