GETDOMAINNAME(3)          OpenBSD Programmer's Manual         GETDOMAINNAME(3)

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

     #include <unistd.h>

     getdomainname(char *name, size_t namelen);

     setdomainname(const char *name, size_t namelen);

     The getdomainname() function returns the YP domain name for the current
     processor, as previously set by setdomainname().  The parameter namelen
     specifies the size of the name array.  If insufficient space is provided,
     the returned name is truncated.  The returned name is always null termi-

     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.

     If the call succeeds a value of 0 is returned.  If the call fails, a val-
     ue of -1 is returned and an error code is placed in the global variable

     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 su-

     domainname(1),  gethostid(3),  gethostname(3),  sysctl(3),  sysctl(8),

     Domain names are limited to MAXHOSTNAMELEN (from <sys/param.h>) charac-
     ters, currently 256.  This includes the terminating NUL character.

     If the buffer passed to getdomainname() is too small, other operating
     systems may not guarantee termination with NUL.

     The getdomainname function call appeared in SunOS 3.x.
