// ---------------------------------------------------------------
// Translate
//
// Translates the data in inSource to the type outType and stores
// the translated data in outDestination.
//
// Preconditions:
//
// Parameters: inSource, the data to be translated
//
// inInfo, hint about the data in inSource (not used)
//
// ioExtension, configuration options for the
// translator
//
// outType, the type to convert inSource to
//
// outDestination, where the translated data is
// put
//
// Postconditions:
//
// Returns: B_BAD_VALUE, if the options in ioExtension are bad
//
// B_NO_TRANSLATOR, if this translator doesn't understand the data
//
// B_ERROR, if there was an error allocating memory or converting
// data
//
// B_OK, if all went well
