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.

"SEE ALSO"
