  32 /*  FUNCTION
  33         This function will transform the string given and place the
  34         result in the supplied buffers, copying at most bufferSize
  35         bytes.
  36
  37         The transformation is such that if the C strcmp() function
  38         was called on two strings transformed by this function then
  39         the result will be the same as calling the Locale StrnCmp()
  40         function on the two strings.
  41
  42     INPUTS
  43         locale      -   the Locale to use for the transformation.
  44         string      -   the string to be transformed
  45         buffer      -   the destination for the transformed string.
  46                         This buffer may need to be larger than the
  47                         untransformed string.
  48         bufferSize  -   the maximum number of bytes to place in
  49                         buffer.
  50         type        -   how to transform the string. See the
  51                         StrnCmp() function for possible values.
  52
  53     RESULT
  54         Length of the number of BYTES placed in the buffer by
  55         the transformation process minus 1 (for NULL termination).
