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 null-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

EFAULT For setdomainname(): name pointed outside of user address space. 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 is unprivileged (Linux: does not have the CAP_SYS_ADMIN capability).

CONFORMING TO

POSIX does not specify these calls.
