       dmapi  -  Describes  the  contents  of the Data Management
       Applications Programming Interface (DMAPI)

SYNOPSIS    [Toc]    [Back]

       dmapi

DESCRIPTION    [Toc]    [Back]

       DMAPI is a Common Applications Environment (CAE)  standard
       that allows data management applications to interface with
       the underlying operating system.  An  example  of  a  data
       management  application  is a hierarchical storage manager
       (HSM), which can use DMAPI features to migrate data to and
       from  tertiary  storage  as well as to track file information.


       The following DMAPI functions are supported in Tru64  UNIX
       V5.1A:

       dm_create_session
       dm_create_userevent
       dm_destroy_session
       dm_find_eventmsg
       dm_get_config
       dm_get_dmattr
       dm_get_events
       dm_get_fileattr
       dm_get_region
       dm_getall_sessions
       dm_getall_tokens
       dm_handle_cmp
       dm_handle_free
       dm_handle_is_valid
       dm_handle_to_fshandle
       dm_init_service
       dm_path_to_fshandle
       dm_path_to_handle
       dm_probe_hole
       dm_punch_hole
       dm_query_session
       dm_read_invis
       dm_release_right
       dm_remove_dmattr
       dm_request_right
       dm_respond_event
       dm_set_disp
       dm_set_dmattr
       dm_set_eventlist
       dm_set_fileattr
       dm_set_region
       dm_set_return_on_destroy
       dm_sync_by_handle
       dm_write_invis

       The following events are supported in Tru64 UNIX V5.1A:

       read event
       write event
       truncate event
       destroy event

       These  optional  DMAPI features are provided in Tru64 UNIX
       V5.1A:

       hole punching
       persistent managed regions
       persistent data attributes

NOTES    [Toc]    [Back]

       The CAE DMAPI standard can be found at:

       http://www.opengroup.org/publications/catalog/c429.htm#medium2

       In the current DMAPI  implementation,  asynchronous  event
       posting is reliable in all but the most unusual cases. For
       more information, see the CAE DMAPI standard  under  Event
       Types.

RESTRICTIONS    [Toc]    [Back]

       An  AdvFS  Advanced  Utilities license is required for the
       use of DMAPI.
