NAMEgetdomainname, setdomainname — get/set the NIS domain name of current host
LIBRARYStandard C Library (libc, -lc)
SYNOPSIS#include < unistd.h>
getdomainname( char *name, int namelen);
setdomainname( const char *name, int namelen);
DESCRIPTIONThe getdomainname() function returns the standard NIS domain name for the current host, as previously set by setdomainname(). The namelen argument specifies the size of the name array. The returned name is null-terminated unless insufficient space is provided.
The setdomainname() function sets the NIS domain name of the host machine to be name, which has length namelen. This call is restricted to the super-user and is normally used only when the system is bootstrapped.
RETURN VALUESUpon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global variable errno is set to indicate the error.
ERRORSThe following errors may be returned by these calls:
- [ EFAULT]
- The name or namelen argument gave an invalid address.
- [ EPERM]
- The caller tried to set the hostname and was not the super-user.
HISTORYThe getdomainname() function appeared in 4.2BSD.
BUGSDomain names are limited to MAXHOSTNAMELEN (from < sys/param.h>) characters, currently 256.
