mnesia_registry(3)	   Erlang Module Definition	    mnesia_registry(3)

NAME
       mnesia_registry - Dump support for registries in	erl_interface.

DESCRIPTION
       This  module  is	 usually part of the erl_interface application,	but is
       currently part of the Mnesia application.

       This module is mainly intended for internal use within OTP, but it  has
       two functions that are exported for public use.

       On C-nodes, erl_interface has support for registry tables. These	tables
       reside in RAM on	the C-node, but	can also be dumped into	Mnesia tables.
       By default, the dumping of registry tables through erl_interface	causes
       a corresponding Mnesia table to be  created  with  mnesia_registry:cre-
       ate_table/1, if necessary.

       Tables that are created with these functions can	be administered	as all
       other Mnesia tables. They can be	included in backups, replicas  can  be
       added, and so on. The tables are	normal Mnesia tables owned by the user
       of the corresponding erl_interface registries.

EXPORTS
       create_table(Tab) -> ok | exit(Reason)

	      A	wrapper	function for mnesia:create_table/2,  which  creates  a
	      table (if	there is no existing table) with an appropriate	set of
	      attributes. The table only resides on the	 local	node  and  its
	      storage  type is the same	as the schema table on the local node,
	      that is, {ram_copies,[node()]} or	{disc_copies,[node()]}.

	      This function is used by erl_interface to	create the Mnesia  ta-
	      ble if it	does not already exist.

       create_table(Tab, TabDef) -> ok | exit(Reason)

	      A	 wrapper  function  for	mnesia:create_table/2, which creates a
	      table (if	there is no existing table) with an appropriate	set of
	      attributes.  The	attributes  and	 TabDef	 are forwarded to mne-
	      sia:create_table/2. For example, if the table is	to  reside  as
	      disc_only_copies on all nodes, a call looks as follows:

			TabDef = [{{disc_only_copies, node()|nodes()]}],
			mnesia_registry:create_table(my_reg, TabDef)
