Name

setdomainname -- set NIS domain name (DEPRECATED).

Synopsis

#include <unistd.h>

int setdomainname (const char * name , size_t namelen );

Description

This call shall fail unless the caller has appropriate privileges.

namelen shall be the length of the string pointed to by name.

Return Value

On success, setdomainname() shall return 0. Otherwise, it shall return -1 and set errno to indicate the error.

Errors

EPERM

The process did not have sufficient privilege to set the domain name.

EINVAL

name is a null pointer.
