getdomainname, setdomainname - get/set domain name
SYNOPSIS
#include <unistd.h>
int getdomainname(char *name, size_t len);
int setdomainname(const char *name, size_t len);
DESCRIPTION
These functions are used to access or to change the domain
name of the current processor. If the NUL-terminated
domain name requires more than len bytes, getdomainname
returns the first len bytes (glibc) or returns an error
(libc).
RETURN VALUE
On success, zero is returned. On error, -1 is returned,
and errno is set appropriately.
ERRORS
EINVAL For getdomainname under libc: name is NULL or name
is longer than len bytes.
EINVAL For setdomainname: len was negative or too large.
EPERM For setdomainname: the caller was not the supe
ruser.
EFAULT For setdomainname: name pointed outside of user
address space.
CONFORMING TO
POSIX does not specify these calls.
