 * 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.
