Direct Access Transport Library Functions    dat_evd_resize(3DAT)



NAME
     dat_evd_resize - modify the size of the event queue of Event
     Dispatcher

SYNOPSIS
     cc [ flag... ] file... -ldat [ library... ]
     #include 

     DAT_RETURN
         dat_evd_resize(
         IN    DAT_EVD_HANDLE    evd_handle,
         IN    DAT_COUNT         evd_min_qlen
         )


PARAMETERS
     evd_handle      Handle for an instance of Event Dispatcher.


     evd_min_qlen    New number of events  the  Event  Dispatcher
                     event queue must hold.


DESCRIPTION
     The dat_evd_resize() function modifies the size of the event
     queue of Event Dispatcher.


     Resizing of Event Dispatcher event queue  should  not  cause
     any  incoming  or  current  events  on the event queue to be
     lost. If the number of entries on the event queue is  larger
     then  the  requested  evd_min_qlen, the operation can return
     DAT_INVALID_STATE  and  not  change  an  instance  of  Event
     Dispatcher

RETURN VALUES
     DAT_SUCCESS                   The operation was successful.


     DAT_INVALID_HANDLE            The  evd_handle  parameter  is
                                   invalid.


     DAT_INVALID_PARAMETER         The evd_min_qlen parameter  is
                                   invalid


     DAT_INSUFFICIENT_RESOURCES    The operation  failed  due  to
                                   resource limitations

     DAT_INVALID_STATE             Invalid parameter. The  number
                                   of  entries on the event queue
                                   of   the   Event    Dispatcher
                                   exceeds  the  requested  event
                                   queue length.


USAGE
     This operation is useful when the potential number of events
     that could be placed on the event queue changes dynamically.
