/*-------------------------------------------------------------------------
* Function: H5Dcreate1
*
* Purpose: Creates a new dataset named NAME at LOC_ID, opens the
* dataset for access, and associates with that dataset constant
* and initial persistent properties including the type of each
* datapoint as stored in the file (TYPE_ID), the size of the
* dataset (SPACE_ID), and other initial miscellaneous
* properties (DCPL_ID).
*
* All arguments are copied into the dataset, so the caller is
* allowed to derive new types, data spaces, and creation
* parameters from the old ones and reuse them in calls to
* create other datasets.
*
* Return: Success: The object ID of the new dataset. At this
* point, the dataset is ready to receive its
* raw data. Attempting to read raw data from
* the dataset will probably return the fill
* value. The dataset should be closed when
* the caller is no longer interested in it.

* Failure: H5I_INVALID_HID
