     NAME
          gethostname, sethostname - get/set name of current host

     SYNOPSIS
          gethostname(name, namelen)
          char *name;
          int namelen;

          sethostname(name, namelen)
          char *name;
          int namelen;

          cc ... -lnet

     DESCRIPTION
          gethostname returns the standard host name for the current
          processor, as previously set by sethostname.  The parameter
          namelen specifies the size of the name array.  The returned
          name is null-terminated unless insufficient space is
          provided.

          sethostname sets the name of the host machine to be name,
          which has length namelen.  This call is restricted to the
          super-user and is normally used only when the system is
          bootstrapped.

     RETURN VALUE
          If the call succeeds a value of 0 is returned.  If the call
          fails, then a value of -1 is returned and an error code is
          placed in the global location errno.

     ERRORS
          The following errors may be returned by these calls:

          [EFAULT]       The name or namelen parameter gave an invalid
                         address.

          [EPERM]        The caller was not the super-user.

     LINKING
          This library is accessed by specifying -lnet as the last
          argument to the compile line, e.g.:

            cc -o prog prog.c -lnet
