 DESCRIPTION    [Toc]    [Back]
      The tt_spec_prop function retrieves the ith value of the property
      associated with this object spec.

      The objid argument is the identifier of the object involved in this
      operation.  The propname argument is the name of the property
      associated with the object spec.  The i argument is the item of the
      list whose value is to be retrieved.  The list numbering begins with
      zero.

      Upon successful completion, the tt_spec_prop function returns the
      contents of the property value.  If there are i values or less,
      tt_spec_prop returns NULL. The application can use tt_ptr_error(3) to
      extract one of the following Tt_status values from the returned
      pointer:
