Create a new native array of type float64 from the contents of the specified DOFValueArray. 
- Resource Management:
 - This function allocates resources that must later be freed by calling PCRMem_Free.
 
- Parameters
 - 
  
    | self | The DOFValue to be extracted. This must be a DOFValueArray, must represent an array of type float64, and must not be NULL.  | 
    | elementOffset | The offset of the first array element to extract (0 starts at the beginning of the array). This should be less than the array length.  | 
    | elementCount | The number of array elements to extract. This should be greater than 0 and not larger than the remaining elements in the array (after elementOffset). | 
  
   
- Returns
 - The new native array of float64 from self.
