DESCRIPTION    [Toc]    [Back]

       These  functions are used to access or to change the domain name of the
       current processor.  If the NUL-terminated  domain  name	requires  more

       returns an error (libc).

       On success, zero is returned.  On error, -1 is returned, and  errno  is
       set appropriately.
