GETDOMAINNAME(2)					      GETDOMAINNAME(2)

NAME
       getdomainname, setdomainname - get/set name of current domain

SYNOPSIS
       getdomainname(name, namelen)
       char *name;
       int namelen;
       setdomainname(name, namelen)
       char *name;
       int namelen;

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

       Setdomainname sets the domain 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.

       The purpose of domains is to enable two distinct networks that may have
       host  names in common to merge.	Each network would be distinguished by
       having a different domain name.	At the current time, only  the	yellow
       pages service makes use of domains.

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 parameter gave an invalid address.

       EPERM	      The  caller  was	not  the  super-user.  This error only
		      applies to setdomainname.

BUGS
       Domain names are limited to 255 characters.
