RedHat 9 (Linux i386) - man page for getdomainname (redhat section 2)

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 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.
