GETDOMAINNAME (2)
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.
RETURN VALUE
On success, zero is returned. On error, -1 is returned, and
errno
is set appropriately.
ERRORS
EINVAL
For
getdomainname ,
name
points to
NULL
or
name
is longer than
len .
EPERM
For
setdomainname ,
the caller was not the superuser.
EINVAL
For
setdomainname ,
len
was too long.
CONFORMING TO
POSIX does not specify these calls.
BUGS
getdomainname
is not compliant with other implementations, since they always return
len
bytes, even if
name
is longer. Linux, however, returns
EINVAL
in this case (as of DLL 4.4.1 libraries).
NOTES
Under Linux,
getdomainname
is implemented at the library level by calling
uname (2).
