Creates a new variable-length array datatype
Procedure:
H5T_VLEN_CREATE (base_type_id)
Signature:
hid_t H5Tvlen_create( hid_t base_type_id )
SUBROUTINE h5tvlen_create_f(type_id, vltype_id, hdferr)
IMPLICIT NONE
INTEGER(HID_T), INTENT(IN) :: type_id ! Datatype identifier of base type
! Base type can only be atomic
INTEGER(HID_T), INTENT(OUT) :: vltype_id ! VL datatype identifier
INTEGER, INTENT(OUT) :: hdferr ! Error code
END SUBROUTINE h5tvlen_create_f
Parameters:
hid_t base_type_id | IN: Base type of datatype to create |
Description:
H5T_VLEN_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 H5T_GET_SUPER to determine the base type of the VL datatype.
The datatype identifier returned from this function should be released with H5T_CLOSE or resource leaks will result. Under certain circumstances, H5D_VLEN_RECLAIM must also be used.
Returns:
Returns datatype identifier if successful; otherwise returns a negative value.
