GETDOMAINNAME(3)        NetBSD 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 host, 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 loca-
     tion 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.

HISTORY

BUGS

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