GETDOMAINNAME(3)         BSD Library Functions Manual         GETDOMAINNAME(3)

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

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <unistd.h>

     int
     getdomainname(char *name, size_t namelen);

     int
     setdomainname(const char *name, size_t namelen);

DESCRIPTION
     getdomainname() returns the standard domain name 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 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 VALUES
     If the call succeeds a value of 0 is returned.  If the call fails, 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 tried to set the domain name and was not
                        the super-user.

BUGS
     Domain names are limited to MAXHOSTNAMELEN (from <sys/param.h>)
     characters including null-termination, currently 256.
