getdomainname, setdomainname − get/set domain name
#include <unistd.h>
int
getdomainname(char *name, size_t
len);
int setdomainname(const char *name, size_t
len);
These functions are used to access or to change the domain name of the current processor. If the null-terminated domain name requires more than len bytes, getdomainname() returns the first len bytes (glibc) or returns an error (libc).
On success, zero is returned. On error, −1 is returned, and errno is set appropriately.

EINVAL |
For getdomainname() under libc: name is NULL or name is longer than len bytes. | ||
|

For setdomainname(): len was negative or too large. | ||

EPERM |
