Returns the size of a datatype
Procedure:
Signature:
size_t H5Tget_size( hid_t dtype_id )
SUBROUTINE h5tget_size_f(type_id, size, hdferr)
IMPLICIT NONE
INTEGER(HID_T), INTENT(IN) :: type_id ! Datatype identifier
INTEGER(SIZE_T), INTENT(OUT) :: size ! Datatype size
INTEGER, INTENT(OUT) :: hdferr ! Error code
! 0 on success and -1 on failure
END SUBROUTINE h5tget_size_f
Parameters:
hid_t dtype_id | IN: Identifier of datatype to query |
Description:
H5T_GET_SIZE returns the size of a datatype in bytes.
For atomic datatypes, array datatypes, compound datatypes, and other datatypes of a constant size, the returned value is the size of the actual datatype in bytes.
For variable-length string datatypes (see Creating variable-length string datatypes), the returned value is the size of the pointer to the actual string, or sizeof(char *). This function does not return the size of actual variable-length string data.
For variable-length sequence datatypes (see H5T_VLEN_CREATE), the returned value is the size of the hvl_t struct, or sizeof(hvl_t). The hvl_t struct contains a pointer to the actual data and a size value. This function does not return the size of actual variable-length sequence data.
Returns:
Returns the size of the datatype in bytes if successful; otherwise 0.
