+>GETDOMAINNAME(3) System Library Functions Manual GETDOMAINNAME(3)
+
+NAME
+ getdomainname, setdomainname - get/set YP domain name of current host
+
+SYNOPSIS
+ #include <unistd.h>
+
+ int
+ getdomainname(char *name, size_t namelen);
+
+ int
+ setdomainname(const char *name, size_t namelen);
+
+DESCRIPTION
+ 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-
+ nated.
+
+ setdomainname() sets the domain name of the host machine to be name,
+ which has length namelen. This call is restricted to the superuser 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 vari-
+ able 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 superuser.
+
+SEE ALSO
+ domainname(1), gethostid(3), gethostname(3), sysctl(3), sysctl(8), yp(8)
+
+BUGS
+ 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.
+
+HISTORY
+ The getdomainname function call appeared in SunOS 3.x.
