read

Allocate an array_list of the default size (32).

Deprecated:
  Use array_list_new2() instead.

struct array_list* array_list_new2 | ( | array_list_free_fn * | free_fn,
|  | int | initial_size
| ) |  |

read

Allocate an array_list of the desired size.

If possible, the size should be chosen to closely match the actual number of elements expected to be used. If the exact size is unknown, there are tradeoffs to be made:

- too small - the array_list code will need to call realloc() more often (which might incur an additional memory copy).
- too large - will waste memory, but that can be mitigated by calling array_list_shrink() once the final size is known.

int array_list_put_idx | ( | struct array_list * | al,
|  | size_t | i,
|  | void * | data
| ) |  |

int array_list_shrink | ( | struct array_list * | arr,
|  | size_t | empty_slots
| ) |  |

Shrink the array list to just enough to fit the number of elements in it, plus empty_slots.
