//  Function:  wch_ncpy()
//
//  Synopsis:  Perform an n-character wide-string copy.
//             Copies 'dwSize' characters from 'pwchSrc' to 'pwchDest'.
//
//  Arguments: pwchDesc  Destination buffer.
//             pwchSrc   Source string.
//             dwSize    Number of characters to copy.
//
//  Returns:   Nothing.
