       catclose ?-fail | -nofail? cathandle
              Close  the  message catalog specified by cathandle.
              Normally,  errors  are  ignored.    If   -fail   is
              specified,  any  errors closing the message catalog
              file are returned.  The  option  -nofail  specifies
              the  default  behavior  of  not returning an error.
              The use of -fail only makes sense if  it  was  also
              specified in the call to catopen.
