NAME
       getdomainname, setdomainname - get or set name of current Network Information Service domain

SYNOPSIS
DESCRIPTION
       returns	the  name  of  the  Network Information Service (NIS) domain for the current processor, as previously set by The parameter namelen
       specifies the size of the name array.  The returned value is null-terminated unless the area pointed to by name is not large enough to hold
       the domain name plus the null byte.  In this case, only the namelen number of bytes is returned.

       sets  the domain of the host machine to name, which has a length of namelen.  This call is restricted to the superuser and is normally used
       only when the system is booted.

       These Network Information Service domains enable two distinct networks with common host names to merge.	Each network is  distinguished	by
       having a different domain name.	Currently, only the Network Information Service uses these domains.

RETURN VALUE
       If the call succeeds, a value of 0 is returned.	If the call fails, a value of -1 is returned and is set to indicate the error.

ERRORS
       If or fail, is set to one of the following values:

	      name	     points outside the accessible address space.

	      The caller is not superuser.
			     This error only applies to

WARNINGS
       The length of the name array should be at least 65; NIS domain names can be up to 64 characters long.

       NIS  servers use the NIS domain name as the name of a subdirectory of Since the NIS domain name can be as long as 64 characters, the domain
       name set with can exceed the maximum file name length allowed on the local file system.	If that length is exceeded, the name of the subdi-
       rectory is the truncated NIS domain name.
