The H5D_WRITE procedure writes data to a dataset.

## Example

H5D_WRITE, Dataset_id, Data [, MEMORY_SPACE_ID=value] [, FILE_SPACE_ID=value]

## Arguments

### Dataset_id

An integer giving the dataspace identifier to which to write the data.

### Data

The data containing the selection to be written. The table shows how IDL data types are converted to HDF5 datatypes. Pointers and object references cannot be written to HDF5 datasets. Data passed in via IDL will automatically be converted into the output data type if possible.
