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 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 superuser.

EFAULT

For setdomainname: name pointed outside of user address space.

CONFORMING TO

POSIX does not specify these calls.
