##### Procedure:

H5S_CREATE_SIMPLE ( rank, current_dims, maximum_dims )

##### Signature:

```
hid_t H5Screate_simple(
int rank,
const hsize_t * current_dims,
const hsize_t * maximum_dims
)
```

```
Fortran90 Interface: h5screate_simple_f
SUBROUTINE h5screate_simple_f(rank, dims, space_id, hdferr, maxdims)
IMPLICIT NONE
INTEGER, INTENT(IN) :: rank ! Number of dataspace dimensions
INTEGER(HSIZE_T), INTENT(IN) :: dims(*) ! Array with current dimension sizes
INTEGER(HID_T), INTENT(OUT) :: space_id ! Dataspace identifier
INTEGER, INTENT(OUT) :: hdferr ! Error code
! 0 on success and -1 on failure
INTEGER(HSIZE_T), OPTIONAL, INTENT(IN) :: maxdims(*)
! Array with the maximum
! dimension sizes
END SUBROUTINE h5screate_simple_f
```

##### Parameters:

*int* `rank` | IN: Number of dimensions of dataspace |

*const hsize_t ** `current_dims` | IN: Array specifying the size of each dimension |

*const hsize_t ** `maximum_dims ` | IN: Array specifying the maximum size of each dimension |

##### Description:

H5S_CREATE_SIMPLE creates a new simple dataspace and opens it for access, returning a dataspace identifier.

`rank`

is the number of dimensions used in the dataspace.

`current_dims`

is a one-dimensional array of size `rank`

specifying the size of each dimension of the dataset. `maximum_dims`

is an array of the same size specifying the upper limit on the size of each dimension.

Any element of `current_dims`

can be `0`

(zero). Note that no data can be written to a dataset if the size of any dimension of its current dataspace is `0`

. This is sometimes a useful initial state for a dataset.

`maximum_dims`

may be the null pointer, in which case the upper limit is the same as `current_dims`

. Otherwise, no element of `maximum_dims`

should be smaller than the corresponding element of `current_dims`

.

If an element of `maximum_dims`

is `H5S_UNLIMITED`

, the maximum size of the corresponding dimension is unlimited.

Any dataset with an unlimited dimension must also be chunked; see H5P_SET_CHUNK. Similarly, a dataset must be chunked if `current_dims`

does not equal `maximum_dims`

.

The dataspace identifier returned from this function must be released with H5S_CLOSE or resource leaks will occur.

##### Returns:

Returns a dataspace identifier if successful; otherwise returns a negative value.
