 NAME

   dced_keytab_get_next_key - Returns a key from a cached list,
                              and advances the cursor in the list

 SYNOPSIS

   #include <dce/dced.h>

   void dced_keytab_get_next_key( dced_keytab_cursor_t  cursor,
                                  dced_key_t            **key,
                                  error_status_t        *status );

 PARAMETERS

   Input/Output

   cursor
          Specifies the cursor that points to a key, and returns
          the cursor advanced to the next key in the list.

   Output

   key    Returns the current key to which the cursor points.

   status
          Returns the status code from this routine.  This status code
          indicates whether the routine completed successfully or, if
          not, why not.  The possible status codes are:

            error_status_ok
            dced_s_no_more_entries

 DESCRIPTION

   The dced_keytab_get_next_key() routine obtains the current key to
   which the key-list cursor points.  This routine is commonly used
   in a loop to traverse a key table's keys.  The keys are returned
   in an undetermined order.  Prior to using this routine in the loop,
   the application must call dced_keytab_initialize_cursor() to obtain
   the key list and established the beginning of the cursor.  When the
   application is finished traversing the key list, it should call
   dced_keytab_release_cursor() to release the resources allocated.

   Management applications use dced_keytab_get_next_key()  to
   remotely access a server's individual keys.  Servers use
   sec_key_mgmt_get_next_key to access their own local keys
   individually.

   You can also use the dced_object_read() routine to read an entire
   key table. You might use dced_object_read() if your application
   needs to bind to and read data for other host services (srvrconf,
   srvrexec, or hostdata) in addition to data for the keytab service.
