GETDOMAINNAME(3)					   BSD Library Functions Manual 					  GETDOMAINNAME(3)

NAME

     getdomainname, setdomainname -- get/set NIS domain name of current host

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <unistd.h>

     int
     getdomainname(char *name, int namelen);

     int
     setdomainname(const char *name, int namelen);

DESCRIPTION

     Getdomainname() returns the standard NIS domain name for the current host, as previously set by setdomainname().  The parameter namelen spec-
     ifies the size of the name array.	The returned name is null-terminated unless insufficient space is provided.

     Setdomainname() 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 VALUES

     Upon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global variable errno is set to indicate the
     error.

ERRORS

     The following errors may be returned by these calls:

     [EFAULT]		The name or namelen parameter gave an invalid address.

     [EPERM]		The caller tried to set the hostname and was not the super-user.

SEE ALSO

     gethostid(3), gethostname(3), sysctl(3)

BUGS

     Domain names are limited to MAXHOSTNAMELEN (from <sys/param.h>) characters, currently 256.

HISTORY

     The getdomainname() function call appeared in 4.2BSD.

NAME

     getdomainname, setdomainname -- get/set domain name of current host

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <unistd.h>

     int
     getdomainname(char *name, size_t namelen);

     int
     setdomainname(const char *name, size_t namelen);

DESCRIPTION

     getdomainname() returns the standard domain name for the current processor, as previously set by setdomainname().	The parameter namelen
     specifies the size of the name array.  The returned name is null-terminated unless insufficient space is provided.

     setdomainname() sets the 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 VALUES

     If the call succeeds a value of 0 is returned.  If the call fails, a value of -1 is returned and an error code is placed in the global loca-
     tion errno.

ERRORS

     The following errors may be returned by these calls:

     [EFAULT]		The name or namelen parameter gave an invalid address.

     [EPERM]		The caller tried to set the domain name and was not the super-user.

HISTORY

     The getdomainname function call appeared in 4.2BSD.

BUGS

     Domain names are limited to MAXHOSTNAMELEN (from <sys/param.h>) characters including null-termination, currently 256.
