- modify the size of the event queue of Event Dispatcher
cc [ flag… ] file… -ldat [ library… ] #include <dat/udat.h> DAT_RETURN dat_evd_resize( IN DAT_EVD_HANDLE evd_handle, IN DAT_COUNT evd_min_qlen )
Handle for an instance of Event Dispatcher.
New number of events the Event Dispatcher event queue must hold.
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
The operation was successful.
The evd_handle parameter is invalid.
The evd_min_qlen parameter is invalid
The operation failed due to resource limitations
Invalid parameter. The number of entries on the event queue of the Event Dispatcher exceeds the requested event queue length.
This operation is useful when the potential number of events that could be placed on the event queue changes dynamically.
