NAME
       dmapi - Describes the contents of the Data Management Applications Pro‐
       gramming Interface (DMAPI)

SYNOPSIS
       dmapi

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