Name: H5Pset_alloc_time
Signature:
  herr_t `H5Pset_alloc_time`(hid_t `plist_id`, H5D_alloc_time_t `alloc_time` )
Purpose:
  Sets the timing for storage space allocation.
Description:
  `H5Pset_alloc_time` sets up the timing for the allocation of storage space for a dataset's raw data. This property is set in the dataset creation property list `plist_id`.

  Timing is specified in `alloc_time` with one of the following values:

  | `H5D_ALLOC_TIME_DEFAULT` | Allocate dataset storage space at the default time. (Defaults differ by storage method.)
  `H5D_ALLOC_TIME_EARLY` | Allocate all space when the dataset is created. (Default for compact datasets.)
  `H5D_ALLOC_TIME_INCR` | Allocate space incrementally, as data is written to the dataset. (Default for chunked storage datasets.) Chunked datasets: Storage space allocation for each chunk is deferred until data is written to the chunk. Contiguous datasets: Incremental storage space allocation for contiguous data is treated as late allocation. Compact datasets: Incremental allocation is not allowed with compact datasets; `H5Pset_alloc_time` will return an error.
  `H5D_ALLOC_TIME_LATE` | Allocate all space when data is first written to the dataset. (Default for contiguous datasets.)

Note:
  `H5Pset_alloc_time` is designed to work in concert with the dataset fill value and fill value write time properties, set with the functions `H5Pset_fill_value` and `H5Pset_fill_time`.

  See H5Dcreate for further cross-references.

Parameters:

hid_t `plist_id` | IN: Dataset creation property list identifier.
H5D_alloc_time_t `alloc_time` | IN: When to allocate dataset storage space.

Returns:
  Returns a non-negative value if successful; otherwise returns a negative value.
