The LOB_LOCATOR argument is validated to the extent possible. If the argument is not valid, the request that invoked the UDF, UDM, or external stored procedure fails and typically returns an error that looks like this:

7554 Invalid LOCATOR argument to LOB access function in UDF
  database_name.udf_name.

Control does not return to the UDF, UDM, or external stored procedure.
