GETDOMAINNAME(E)    Linux Programmer's Manual    GETDOMAINNAME(E)



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 supe-
              ruser.

       EFAULT For setdomainname: name  pointed  outside  of  user
              address space.

CONFORMING TO
       POSIX does not specify these calls.
