evd_handle evd_min_qlen

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

DAT_SUCCESS DAT_INVALID_HANDLE DAT_INVALID_PARAMETER DAT_INSUFFICIENT_RESOURCES DAT_INVALID_STATE

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