getdomainname(2yp) getdomainname(2yp)

Name
getdomainname, setdomainname - get or set name of current domain

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

Description
The system call returns the domain name of the current processor, as set by

The system call sets the domain of the host machine to be name, which has a length specified by namelen. This system call is restricted to
the superuser and is normally used only when the system is bootstrapped.

The purpose of domains is to allow merging of two distinct networks that have common host names. Each network can be distinguished by hav-
ing a different domain name. At the current time, only the Yellow Pages service makes use of domains.

The name argument is the address where the name of the current domain is stored.

The namelen argument specifies the size of the name array. The returned name is null-terminated unless insufficient space is provided.

Restrictions
Domain names are limited to 31 characters.

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
location, errno.

Diagnostics
[EFAULT] The name parameter contains an invalid address.

[EPERM] The caller was not the superuser. This error message only applies to the system call.
