DESCRIPTION
-----------

Get a pointer to a UG type double parameter vector.

INPUT ARGUMENTS
---------------

_Double_Param_Name             : Name of UG type double parameter vector.

UG_Param_Struct_Ptr            : UG parameter structure.

RETURN VALUE
---------------

1                              : Then a parameter was found with a matching name
                                 and the output arguments were set.
<0                             : Then no match was found and the output
                                 arguments were not set.

OUTPUT ARGUMENTS
---------------

_Double_Param_Vector_Entries   : Number of entries in the UG type double
                                 parameter vector.

_Double_Param_Vector           : Pointer to the UG type double parameter vector
                                 within the UG parameter structure.

                                 If _Double_Param_Vector_Entries = 0 then the
                                 pointer is not set.

                                 Do not reallocate or free this pointer.
                                 Modification of the entries will also modify
                                 the UG parameter structure.
