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

NAME

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

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <unistd.h>

     int
     getdomainname(char *name, int namelen);

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

DESCRIPTION

     Getdomainname() returns the standard NIS domain name for the current host, as previously set by setdomainname().  The parameter namelen spec-
     ifies the size of the name array.	The returned name is null-terminated unless insufficient space is provided.

     Setdomainname() sets the NIS 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

     Upon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global variable errno is set to indicate the
     error.

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 hostname and was not the super-user.

SEE ALSO

     gethostid(3), gethostname(3), sysctl(3)

BUGS

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

HISTORY

     The getdomainname() function call appeared in 4.2BSD.
