  NAME
      dce_attr_intro - Introduction to the DCE Attribute Interface routines

  DESCRIPTION

      The DCE Attribute Interface API allows applications to define and
      access attributes types (schema entries) in a schema of your choice.
      It is based on the Extended Registry Attribute (ERA) interface, which
      defines and accesses attribute types in the registry database schema.
      Except for the binding methods, the two APIs are similar.

      Note however, that the Extended Registry Attribute API provides
      routines to create attribute types in the registry schema, to create
      and manipulate attribute instances, and to attach those instances to
      objects.  The DCE Attribute Interface in its current state provides
      calls only to create attribute types.

      For general usage guidelines for the DCE Attribute Interface refer to
      the chapter in this manual titled "The Extended Attribute Application
      Program Interface." The DCE Attribute Interface routine reference
      pages are supplied in this section of the manual.

      The DCE Attribute Interface Routines

      The DCE Attribute Interface consists of the following routines:

      dce_attr_sch_bind
             Returns an opaque handle of type dce_attr_sch_handle_t to a
             schema object specified by name and sets authentication and
             authorization parameters for the handle.

      dce_attr_sch_bind_free
             Releases an opaque handle of type dce_attr_sch_handle_t.

      dce_attr_sch_create_entry
             Creates a schema entry in a schema bound to with
             dce_attr_sch_bind.

      dce_attr_sch_update_entry
             Updates a schema entry in a schema bound to with
             dce_attr_sch_bind.

      dce_attr_sch_delete_entry
             Deletes a schema entry in a schema bound to with
             dce_attr_sch_bind.

      dce_attr_sch_scan
             Reads a specified number of schema entries.

      dce_attr_sch_cursor_init
             Allocates resources to and initializes a cursor used with
             dce_attr_sch_scan. The dce_attr_sch_cursor_init routine makes
             a remote call that also returns the current number of schema
             entries in the schema.

      dce_attr_sch_cursor_alloc
             Allocates resources to a cursor used with dce_attr_sch_scan.
             The dce_attr_sch_cursor_alloc routine is a local operation.

      dce_attr_sch_cursor_release
             Releases states associated with a cursor created by
             dce_attr_sch_cursor_alloc or dce_attr_sch_cursor_init.

      dce_attr_sch_cursor_reset
             Reinitializes a cursor used with dce_attr_sch_scan.  The reset
             cursor can then be reused without releasing and re-allocating.

      dce_attr_sch_lookup_by_id
             Reads a schema entry identified by attribute type UUID.

      dce_attr_sch_lookup_by_name
             Reads a schema entry identified by attribute name.

      dce_attr_sch_get_acl_mgrs
             Retrieves the manager types of the ACLs protecting objects
             dominated by a named schema.

      dce_attr_sch_aclmgr_strings
             Returns printable ACL strings associated with an ACL manager
             protecting a schema object.

      Data Types and Structures

      dce_attr_sch_handle_t
        An opaque handle to a schema object.  Use dce_attr_sch_bind to
        acquire the handle.

      dce_attr_component_name_t
        A pointer to a character string used to further specify a schema
        object.

      dce_bind_auth_info_t
        A enumeration that defines whether or not the binding is
        authenticated.  This data type is defined exactly as the
        sec_attr_bind_auth_info_t data type in the ERA interface.
        See the sec_intro reference page for more information
        on sec_attr_bind_auth_info_t.

      dce_attr_schema_entry_t
        A structure that defines a complete attribute entry for the schema
        catalog. This data type is defined exactly as the
        sec_attr_schema_entry_t data type in the ERA interface.  See the
        sec_intro reference page for more information on
        sec_attr_schema_entry_t.

      dce_attr_cursor_t
        A structure that provides a pointer into a database and is used for
        multiple database operations. This cursor must minimally represent
        the object indicated by dce_attr_sch_handle_t. The cursor may
        additionally represent an entry within that schema.

      dce_attr_schema_entry_parts_t
        A 32-bit bitset containing flags that specify the schema entry
        fields that can be modified on a schema entry update operation.
        This data type is defined exactly as the
        sec_attr_schema_entry_parts_t data type in the ERA interface.
        See the sec_intro reference page for more information on
        sec_attr_schema_entry_parts_t.

          the fields in the schema bound to by h that can be modified.

   schema_entry
          A pointer to a dce_attr_schema_entry_t that contains the
          schema entry values for the schema entry to be updated.

   Output

   status
          A pointer to the completion status.  On successful completion,
          the routine returns error_status_ok.  Otherwise, it returns an
          error.

 DESCRIPTION

   The dce_attr_sch_update_entry() routine modifies schema entries.
   Only those schema entry fields set to be modified in the
   dce_attr_schema_entry_parts_t data type can be modified.

   Some schema entry components can never be modified.  Instead to make
   any changes to these components, the schema entry must be deleted
   (which deletes all attribute instances of that type) and recreated.
   These components are listed below:

     +  Attribute name
     +  Reserved flag
     +  Apply defaults flag
     +  Intercell action flag
     +  Trigger binding
     +  Comment

   Fields that are arrays of structures (such as acl_mgr_set and
   trig_binding) are completely replaced by the new input array.
   This operation cannot be used to add a new element to the existing
   array.

   Permissions Required

   The dce_attr_sch_update_entry() routine requires appropriate
   permissions on the schema object. These permissions are managed
   by the target server.

 NAME
   dce_attr_sch_delete_entry - Delete a schema entry

 SYNOPSIS

   #include <dce/dce_attr_sch.h>

   void dce_attr_sch_delete_entry( dce_attr_sch_handle_t h,
                                   uuid_t *attr_id,
                                   error_status_t *status );

 PARAMETERS

   Input

   h      An opaque handle bound to a schema object.  Use
          dce_attr_sch_bind() to acquire the handle.

   attr_id
          A pointer to a uuid_t that identifies the schema entry to be
          deleted in the schema bound to by h.

   Output

   status
          A pointer to the completion status.  On successful completion,
          the routine returns error_status_ok.  Otherwise, it returns an
          error.

 DESCRIPTION

   The dce_attr_sch_delete_entry() routine deletes a schema entry.
   Because this is a radical operation that invalidates any existing
   attributes of this type on objects dominated by the schema, access
   to this operation should be severely limited.

   Permissions Required

   The dce_attr_sch_delete_entry() routine requires requires
   appropriate permissions on the schema object.  These permissions

 NAME
   dce_attr_sch_scan - Read a specified number of schema entries

 SYNOPSIS

   #include <dce/dce_attr_base.h>

   void dce_attr_sch_scan( dce_attr_sch_handle_t h,
                           dce_attr_cursor_t *cursor,
                           unsigned32 num_to_read,
                           unsigned32 *num_read,
                           dce_attr_schema_entry_t schema_entries[],
                           error_status_t *status );

 PARAMETERS

   Input

   h      An opaque handle bound to a schema object.  Use
          dce_attr_sch_bind() to acquire the handle.

   num_to_read
          An unsigned 32-bit integer specifying the size of the
          schema_entries[] array and the maximum number of entries to
          be returned.

   Input/Output

   cursor
          A pointer to a dce_attr_cursor_t.  As input cursor must
          be allocated and can be initialized. If cursor is not
          initialized, dce_attr_sch_scan will initialize it.  As
          output, cursor is positioned at the first schema entry
          after the returned entries.

   Output

   num_read
          A pointer to an unsigned 32-bit integer specifying the number
          of entries returned in schema_entries[].

   schema_entries[]
          A dce_attr_schema_entry_t that contains an array of the
          returned schema entries.

   status
          A pointer to the completion status.  On successful completion,
          the routine returns error_status_ok.  Otherwise, it returns an
          error.

 DESCRIPTION

   The dce_attr_sch_scan() routine reads schema entries. The read
   begins at the entry at which the input cursor is positioned and
   ends after the number of entries specified in num_to_read.

   The input cursor must have been allocated by either the
   dce_attr_sch_cursor_init() or the dce_attr_sch_cursor_alloc() call.
   If the input cursor is not initialized, dce_attr_sch_scan()
   initializes it; if cursor is initialized, dce_attr_sch_scan() simply
   advances it.

   To read all entries in a schema, make successive dce_attr_sch_scan()
   calls.  When all entries have been read, the call returns the message
   no_more_entries.

   This routine is useful as a browser.

   Permissions Required

   The dce_attr_sch_scan() routine requires requires appropriate
   permissions on the schema object. These permissions are managed
   by the target server.

 NAME
   dce_attr_sch_cursor_init - Initialize and allocate a cursor used
                              with the dce_attr_sch_scan call

 SYNOPSIS

   #include <dce/dce_attr_base.h>

   void dce_rgy_attr_cursor_init( dce_attr_sch_handle_t h,
                                  unsigned32 *cur_num_entries,

                                  error_status_t *status );

 PARAMETERS

   Input

   h      An opaque handle bound to a schema object.  Use
          dce_attr_sch_bind() to acquire the handle.

   Output

   cur_num_entries
          A pointer to an unsigned 32-bit integer that specifies the
          total number of entries contained in the schema at the time
          of this call.

   cursor
          A pointer to a dce_attr_cursor_t that is initialized to the
          first entry in the the schema.

   status
          A pointer to the completion status.  On successful completion,
          the call returns error_status_ok.  Otherwise, it returns an
          error.

 DESCRIPTION

   The dce_attr_sch_cursor_init() call initializes and allocates a
   cursor used with the dce_attr_sch_scan call.  This call makes
   remote calls to initialize the cursor.  To limit the number of
   remote calls, use the dce_attr_sch_cursor_alloc() call to allocate
   cursor, but not initialize it.  If the cursor input to
   dce_attr_sch_scan has not been initialized, dce_attr_sch_scan call
   will initialize it; if it has been initialized, dce_attr_sch_scan
   advances it.

   Unlike the dce_attr_sch_cursor_alloc() call, the
   dce_attr_sch_cursor_init() call supplies the total number
   of entries found in the schema as an output parameter.

   Permissions Required

   None.

 NAME
   dce_attr_sch_cursor_alloc - Allocates resources to a cursor used
                               with the dce_attr_sch_scan call

 SYNOPSIS

   #include <dce/dce_attr_sch.h>

   void dce_rgy_attr_cursor_alloc( dce_attr_cursor_t *cursor,
                                   error_status_t *status );

 PARAMETERS

   Output

   cursor    A pointer to a dce_attr_cursor_t.

   status    A pointer to the completion status.  On successful
             completion, the call returns error_status_ok.  Otherwise,
             it returns an error.

 DESCRIPTION

   The dce_attr_sch_cursor_alloc() call allocates resources to a
   cursor used with the dce_attr_sch_scan call.  This routine,
   which is a local operation, does not initialize cursor.

   The dce_attr_sch_cursor_init() routine, which makes a remote
   call, allocates and initializes the cursor.  In addition,
   dce_attr_sch_cursor_init() returns the total number of entries
   found in the schema as an output parameter;
   dce_attr_sch_cursor_alloc() does not.

   Permissions Required

   The dce_attr_sch_cursor_alloc() call requires appropriate
   permissions on the schema object. These permissions are managed
   by the target server.

                                 that has been allocated with either
                                 dce_attr_sch_cursor_init() or
                                 dce_attr_sch_cursor_alloc().

 SYNOPSIS

   #include <dce/dce_attr_base.h>

   void dce_attr_sch_cursor_init( dce_attr_cursor_t *cursor,
                                  error_status_t *status );

 PARAMETERS

   Input/Output

   cursor
          A pointer to a dce_attr_cursor_t. As an input parameter,
          cursor must have been initialized to the first entry in a
          schema.  As an output parameter, cursor is uninitialized
          with all resources released.

   Output

   status
          A pointer to the completion status.  On successful completion,
          the routine returns error_status_ok.  Otherwise, it returns an
          error.

 DESCRIPTION

   The dce_attr_sch_cursor_init() routine releases the resources
   allocated to a cursor that has been allocated by either a
   dce_attr_sch_cursor_init() or dce_attr_sch_cursor_alloc().  This
   call is a local operation and makes no remote calls.

   Permissions Required

   None.

  10 - dce_attr_sch_cursor_reset

 NAME
   dce_attr_sch_cursor_reset - Resets a cursor that has been allocated
                               with either dce_attr_sch_cursor_init()
                               or dce_attr_sch_cursor_alloc().

 SYNOPSIS

   #include <dce/dce_attr_base.h>

   void dce_attr_cursor_reset( dce_attr_cursor_t *cursor,
                               error_status_t *status );

 PARAMETERS

   Input/Output

   cursor
          A pointer to a dce_attr_cursor_t. As an input parameter, an
          initialized cursor. As an output parameter, cursor is reset
          to the first attribute in the schema.

   status
          A pointer to the completion status.  On successful completion,
          the routine returns error_status_ok.  Otherwise, it returns an
          error.

 DESCRIPTION

   The dce_attr_sch_cursor_reset() routine resets a dce_attr_cursor_t
   that has been allocated by either a dce_attr_sch_cursor_init() or
   dce_attr_sch_cursor_alloc(). The reset cursor can then be used to
   process a new dce_attr_sch_scan query by reusing the cursor instead
   of releasing and re-allocating it. This is a local operation and
   makes no remote calls.

   Permissions Required

   None.

  13 - dce_attr_sch_get_acl_mgrs

 NAME
   dce_attr_sch_get_acl_mgrs - Retrieve the manager types of the
                               ACLs protecting the objects dominated
                               by a named schema

 SYNOPSIS

   #include  <dce/dce_attr_base.h>

   void dce_attr_sch_get_acl_mgrs( dce_attr_sch_handle_t h,
                                   unsigned32 size_avail,
                                   unsigned32 *size_used,
                                   unsigned32 *num_acl_mgr_types,
                                   uuid_t acl_mgr_types[],
                                   error_status_t *status );

 PARAMETERS

   Input

   h      An opaque handle bound to a schema object.  Use
          dce_attr_sch_bind() to acquire the handle.

   size_avail
          An unsigned 32-bit integer containing the allocated length
          of the acl_manager_types[] array.

   Output

   size_used
          An unsigned 32-bit integer containing the number of output
          entries returned in the acl_mgr_types[] array.

   num_acl_mgr_types
          An unsigned 32-bit integer containing the number of types
          returned in the acl_mgr_types[] array.  This may be greater
          than size_used if there was not enough space allocated by
          size_avail for all the manager types in the
          acl_manager_types[] array.

   acl_mgr_types[]
          An array of the length specified in size_avail to contain
          UUIDs (of type uuid_t) identifying the types of ACL managers
          protecting the target object.

   status
          A pointer to the completion status.  On successful completion,
          the routine returns error_status_ok.  Otherwise, it returns an
          error.

 DESCRIPTION

   The dce_attr_sch_get_acl_mgrs() routine returns a list of the
   manager types protecting the schema object identified by h.

   ACL editors and browsers can use this operation to determine the ACL
   manager types protecting a selected schema object. Then, using the
   dce_attr_sch_aclmgr_strings() routine, they can determine how to
   format for display the permissions supported by that ACL manager type.

   Permissions Required

   The dce_attr_sch_get_acl_mgrs() routine requires appropriate
   permissions on the schema object for which the ACL manager types
   are to be returned.  These permissions are managed by the target
   server.
