NAME

getdomainname -- get domain name

SYNOPSIS

#include <unistd.h>

int getdomainname(char *name, size_t len);

DESCRIPTION

RETURN VALUE

On success, zero is returned. On error, -1 is returned, and errno is set appropriately.

ERRORS

EINVAL

Under libc: name is NULL or name is longer than len bytes.
