Macro Definition Documentation

◆ H5Tarray_create

#define H5Tarray_create   H5Tarray_create2

H5Tarray_create() is a macro that is mapped to either H5Tarray_create1() or H5Tarray_create2().

Function Documentation

◆ H5Tarray_create1()

hid_t H5Tarray_create1 ( hid_t  base_id,
int  ndims,
const hsize_t  dim[],
const int  perm[] 
)

Creates an array datatype object.

Parameters
[in]base_idDatatype identifier for the array base datatype
[in]ndimsRank of the array
[in]dimSize of each array dimension
[in]permDimension permutation (Currently not implemented.)
Returns
Returns a array datatype identifier if successful; otherwise returns H5I_INVALID_HID.
Deprecated:
This function has been renamed from H5Tarray_create() and is deprecated in favor of the macro H5Tarray_create or the function H5Tarray_create2().

H5Tarray_create1() creates a new array datatype object.

base_id is the datatype of every element of the array, i.e., of the number at each position in the array.

rank is the number of dimensions and the size of each dimension is specified in the array dims. The value of rank is currently limited to H5S_MAX_RANK and must be greater than 0 (zero). All dimension sizes specified in dims must be greater than 0 (zero).

The array perm is designed to contain the dimension permutation, i.e. C versus FORTRAN array order. (The parameter perm is currently unused and is not yet implemented.)

Version
1.8.0 Function H5Tarray_create() renamed to H5Tarray_create1() and deprecated in this release.
Since
1.4.0

◆ H5Tarray_create2()

hid_t H5Tarray_create2 ( hid_t  base_id,
unsigned  ndims,
const hsize_t  dim[] 
)

Creates an array datatype object.

Parameters
[in]base_idDatatype identifier for the array base datatype
[in]ndimsRank of the array
[in]dimSize of each array dimension
Returns
Returns a array datatype identifier if successful; otherwise returns H5I_INVALID_HID.

H5Tarray_create2() creates a new array datatype object.

base_id is the datatype of every element of the array, i.e., of the number at each position in the array.

ndims is the number of dimensions and the size of each dimension is specified in the array dim. The value of rank is currently limited to H5S_MAX_RANK and must be greater than 0 (zero). All dimension sizes specified in dim must be greater than 0 (zero).

Since
1.8.0

◆ H5Tget_array_dims1()

int H5Tget_array_dims1 ( hid_t  type_id,
hsize_t  dims[],
int  perm[] 
)

Retrieves sizes of array dimensions.

Parameters
[in]type_idDatatype identifier
[out]dimsSizes of array dimensions
[out]permDimension permutations (This parameter is not used.)
Returns
Returns the non-negative number of dimensions of the array type if successful; otherwise, returns a negative value.
Deprecated:
This function has been renamed from H5Tget_array_dims() and is deprecated in favor of the macro H5Tget_array_dims or the function H5Tget_array_dims2().

H5Tget_array_dims1() returns the sizes of the dimensions and the dimension permutations of the specified array datatype object.

The sizes of the dimensions are returned in the array dims.

Version
1.8.0 Function H5Tarray_create() renamed to H5Tarray_create1() and deprecated in this release.
Since
1.4.0

◆ H5Tget_array_dims2()

int H5Tget_array_dims2 ( hid_t  type_id,
hsize_t  dims[] 
)

Retrieves sizes of array dimensions.

Parameters
[in]type_idDatatype identifier
[out]dimsSizes of array dimensions
Returns
Returns the non-negative number of dimensions of the array type if successful; otherwise returns a negative value.

H5Tget_array_dims2() returns the sizes of the dimensions of the specified array datatype object in the array dims.

Since
1.2.0

◆ H5Tget_array_ndims()

int H5Tget_array_ndims ( hid_t  type_id)

Returns the rank of an array datatype.

Parameters
[in]type_idDatatype identifier
Returns
Returns the rank of the array if successful; otherwise returns a negative value.

H5Tget_array_ndims() returns the rank, i.e., the number of dimensions, of an array datatype object.

Since
1.2.0
