 DESCRIPTION    [Toc]    [Back]
      The sethostname() system call sets the name of the host processor to
      name, which has a length of namelen characters.  At system boot time
      sethostname() is normally executed by the hostname command (see

      limited to MAXHOSTNAMELEN characters, as defined in <sys/param.h>.

      sethostname() returns the following values:

            0   Successful completion.
           -1   Failure.  errno is set to indicate the error.

 ERRORS    [Toc]    [Back]
      If sethostname() fails, errno is set to one of the following values.

           [EFAULT]       name points to an illegal address.  The reliable
                          detection of this error is implementation

           [EPERM]        The user does not have appropriate privileges.
