Description:
HTML Wrap
classhdf-rm-section

H5Tvlen_create creates a new one-dimensional array datatype of variable-length (VL) with the base datatype base_type_id.

This one-dimensional array often represents a data sequence of the base datatype, such as characters for character sequences or vertex coordinates for polygon lists. The base type specified for the VL datatype can be any HDF5 datatype, including another VL datatype, a compound datatype, or an atomic datatype.

When necessary, use H5Tget_super to determine the base type of the VL datatype.

The datatype identifier returned from this function should be released with H5Tclose or resource leaks will result. Under certain circumstances, H5Dvlen_reclaim must also be used.

Note

H5Tvlen_create cannot be used to create a variable-length string datatype. H5Tvlen_create called with a string or character base type creates a variable-length sequence of strings (a variable-length, 1-dimensional array), with each element of the array being of the string or character base type.

To create a variable-length string datatype, see “Creating variable-length string datatypes.”
