NAME

       Net::NIS::Table - Object Interface to Sun's Network Information Service

DESCRIPTION

       The NIS interface comes in two parts.  The first part is the raw implementation of the NIS
       API, described in Net::NIS.  The second is the object interface.  This document describes
       the object interface implementation.

       The Table object represents an individual NIS map.  A NIS map is bound to a Table object
       with the new method:

         $obj = Net::NIS::Table->new($map, [ $domain ]);

       For example,

         $hostsmap = Net::NIS::Table->new("hosts.byname");

       This will create a Table object bound to the "hosts.byname" NIS map in the default NIS
       domain.  All operations on the $hostsmap object will relate to the "hosts.byname" map.

       You can also specify a non-default domain:

         $hostsmap = Net::NIS::Table->new("hosts.byname", "my.domain.com.au");

       Once a Table object has been bound to a NIS map, the following methods are available:

       $value = $obj->match($key)
            Returns the value for a given key.  If you only wish to look up one or two values,
            this function is more efficient, as it retrieves the items one at a time.  If you
            wish to retrieve many items (where many is dependent on the size of the map, and
            probably what sort of machine you are on), it is better to use the list interface,
            which uses just one RPC call to retreive the entire map.

       \%data = $obj->list()
            Return a reference to an associative array which contains the entire NIS map.  The
            keys in the %data array correspond to the keys in the NIS map.  If any error occurs
            that prevents the retrieval of the map, then the undefined value is returned.  In
            this case, your program can use the status method to determine the cause of the
            error.

       \%data = $obj->search($srchkey)
            Return a reference to an associative array which contains all entries that have keys
            that contain the $srchkey.  If any error occurs that prevents the retrieval of the
            map, then the undefined value is returned.  In this case, your program can use the
            status method to determine the cause of the error.

       $status = $obj->status()
            Returns the status code for the last operation.  If the last operation succeeded,
            then the status code is 0.  The status codes returned by this method are described
            below in the ERROR CODES section.

       $status = $obj->status_string()
            Returns the character representation of the status code for the last operation.  If
            the last operation succeeded, then the status code is something like "operation
            succeeded".  The exact strings returned by this function are implementation
            dependent, and should not be used for comparison purposes.  Use the status call, as
            described above.

ERROR CODES

       The status method described above can return one of the following values:

         $Net::NIS::ERR_ACCESS         Access violation
         $Net::NIS::ERR_BADARGS        Args to function are bad
         $Net::NIS::ERR_BADDB          yp data base is bad
         $Net::NIS::ERR_BUSY           Database is busy
         $Net::NIS::ERR_DOMAIN         Can't bind to a server which serves this domain
         $Net::NIS::ERR_KEY            No such key in map
         $Net::NIS::ERR_MAP            No such map in server's domain
         $Net::NIS::ERR_NODOM          Local domain name not set
         $Net::NIS::ERR_PMAP           Can't communicate with portmapper
         $Net::NIS::ERR_NOMORE         No more records in map database
         $Net::NIS::ERR_RESRC          Local resource allocation failure
         $Net::NIS::ERR_RPC            RPC failure
         $Net::NIS::ERR_YPBIND         Can't communicate with ypbind
         $Net::NIS::ERR_YPERR          Internal yp server or client interface error
         $Net::NIS::ERR_YPSERV         Can't communicate with ypserv
         $Net::NIS::ERR_VERS           YP version mismatch
