Determines whether a datatype is a committed type or a transient type
Procedure:
Signature:
htri_tH5Tcommitted( hid_t dtype_id )
SUBROUTINE h5tcommitted_f(dtype_id, committed, hdferr)
IMPLICIT NONE
INTEGER(HID_T), INTENT(IN) :: dtype_id
! A datatype identifier
LOGICAL, INTENT(OUT) :: committed ! Positive, if the datatype committed
! Zero, if the datatype not committed.
INTEGER, INTENT(OUT) :: hdferr ! Error code
! 0 on success and -1 on failure
END SUBROUTINE h5tcommitted_f
Parameters:
hid_t dtype_id | IN: Datatype identifier |
Description:
H5T_COMMITTED queries a type to determine whether the type specified by the dtype_id identifier is a committed (formerly known as a named) type or a transient type. If this function returns a positive value, then the type is committed (that is, it has been committed, perhaps by some other application). Datasets which return committed datatypes with H5D_GET_TYPE are able to share the datatype with other datasets in the same file.
Returns:
Returns a positive value if the datatype has been committed.
Returns 0 if the datatype has not been committed.
Returns a negative value when the function fails.
