get/set YP domain name of current
char *name, size_t
function returns the YP domain name for the current processor, as previously
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 NUL terminated.
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.
Under normal operation once the domainname is set, it cannot be changed.
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 variable errno.
The following errors may be returned by these calls:
- The name parameter gave an invalid address.
- The caller tried to set the domain name and was not the superuser.
domainname(1), sysctl(2), gethostid(3), gethostname(3), sysctl(8), yp(8)
getdomainname function call appeared
in SunOS 3.x.
Domain names are limited to
characters, currently 256. This includes the terminating NUL character.
If the buffer passed to
too small, other operating systems may not guarantee termination with
