PosCxPutPendingEventMemory tries to delegate a memory object containing the event data to a waiting caller. If the target caller does not have a read request waiting, the new event is added to the designated event queue (control or data).
device [in]A handle to a framework device object that represents the device.
deviceInterfaceTag [in]The device interface associated with the event. By default, only file objects that have the same tag will receive this event.
eventMemory [in]The new event data memory object that contains both the point-of-service event header and the data. PosCx will take over ownership of this passed in memory object.
eventAttr [in]The event attributes.
Possible return values are:
| Value | Description |
|---|---|
| STATUS_SUCCESS | The event was created and delegated to a waiting caller, or the event was discarded because there is no device owner. |
| STATUS_PENDING | The event was queued because no caller is currently waiting. |
| STATUS_DEVICE_NOT_READY | The PosCx library was not successfully initialized. |
| Other errors | Other appropriate failure error codes. |
