HBA_GetEventBuffer - remove and return the next event from the HBA's event queue
cc [ flag… ] file… –lHBAAPI [ library… ] #include <hbaapi.h> HBA_STATUS HBA_GetEventBuffer(HBA_HANDLE handle, HBA_EVENTINFO *EventBuffer, HBA_UINT32 *EventBufferCount);
an open handle returned from HBA_OpenAdapter(3HBAAPI)
a pointer to an HBA_EVENTINFO buffer
a pointer to the maximum number of events that can be stored in the HBA_EVENTINFO buffer. The value will be changed to the actual number of events placed in the buffer on completion.
The HBA_GetEventBuffer() function retrieves events from the HBA's event queue. The number of events returned is the lesser of EventBufferCount and the number of events on the queue. The returned events are removed from the queue.
Upon successful completion, HBA_STATUS_OK is returned. Otherwise, an error value is returned and the value of EventBufferCount is undefined.
See libhbaapi(3LIB) for general error status values.
