GETDOMAINNAME(2) Linux Programmer's Manual GETDOMAINNAME(2)
NAME
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 null-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
EFAULT For setdomainname(): name pointed outside of user address space.
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 is unprivileged (Linux: does not
have the CAP_SYS_ADMIN capability).
CONFORMING TO
POSIX does not specify these calls.
