Syntax:
typedef cblt_rtncode (*PFI_IDPES_FN_UTF16_TO_DISPLAY)(
                                                cobuns8_t  in_string,
                                                cobuns32_t in_len,
                                                cobuns8_t  out_string,
                                                cobuns32_t *out_len);
 On Entry:
| in_string | UTF16 encoded string | 
| in_len | Size of in_string | 
| out_len | Maximum size of out_string, or 0 for function to return the required size of out_string | 
 
On Exit:
| out_string | COBOL DISPLAY encoded string | 
| out_len | Size of out_string, or required size if 0 specified on input, or if function returns IDPES_BUFFER_TOO_SMALL | 
 
Return codes:
| 0 | IDPES_SUCCESS | 
| 1 | IDPES_BUFFER_TOO_SMALL |
