->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.
