Direct Access Transport Library Functions    datevdresize(3DAT)



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

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

     DATRETURN
         datevdresize(
         IN    DATEVDHANDLE    evdhandle,
         IN    DATCOUNT         evdminqlen
         )


PARAMETERS
     evdhandle      Handle for an instance of Event Dispatcher.


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


DESCRIPTION
     The datevdresize() 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  evdminqlen, the operation can return
     DATINVALIDSTATE  and  not  change  an  instance  of  Event
     Dispatcher

RETURN VALUES
     DATSUCES                   The operation was successful.


     DATINVALIDHANDLE            The  evdhandle  parameter  is
                                   invalid.


     DATINVALIDPARAMETER         The evdminqlen parameter  is
                                   invalid


     DATINSUFICIENTRESOURCES    The operation  failed  due  to
                                   resource limitations

     DATINVALIDSTATE             Invalid parameter. The  number
                                   of  entries on the event queue
                                   of   the   Event    Dispatcher
