renamehost - rename the existing hostname in NIS hosts database
int renamehost(char *oldname, char *newname, char *aliases,
Renamehost sends an host rename request to registrar(1M) on NIS master
via the yp_update(3R) call. The result is that the new host name will be
associated with the original internet address. This routine should be
used only when NIS is enabled in the network. This function call can not
only change the hostname, but also modify the aliases.
The arguments for the routine are:
The original host name.
The new host name for the internet address. This new name
should not be already used by other host. However, it can be
the alias of the original host. User may want to use this call
to swap the alias and host name. User also can use this call
just to modify the alias when newname is the same as oldname.
The new aliases, each separated by spaces, of the host. The
maximum number of characters allowed in the string is
MAX_ALIASES defined in <sun/hostreg.h>. The new aliases can be
the same as the original aliases, or contains the old host
name. A NULL indicates the alias is omitted.
The root password of NIS master. If NIS master does not have
root password, simply pass a NULL.
On successful completion, Renamehost returns NULL. The unsuccessful
return code are defined in <rpcsvc/ypclnt.h>.
Renamehost always wait until NIS databases are pushed to all slave
registrar(1M), yp_update(1M), registerinethost(3N), unregisterhost(3N),
