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

32 Resizing of Event Dispatcher event queue should not cause any incoming
33 or current events on the event queue to be lost. If the number of
34 entries on the event queue is larger then the requested evd_min_qlen,
35 the operation can return DAT_INVALID_STATE and not change an instance
36 of Event Dispatcher
37
39 DAT_SUCCESS The operation was successful.

41
42 DAT_INVALID_HANDLE The evd_handle parameter is invalid.
43
44
45 DAT_INVALID_PARAMETER The evd_min_qlen parameter is invalid
46
47
48 DAT_INSUFFICIENT_RESOURCES The operation failed due to resource lim‐
49 itations
50
51
52 DAT_INVALID_STATE Invalid parameter. The number of entries
53 on the event queue of the Event Dis‐
54 patcher exceeds the requested event queue
55 length.

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