If an event is 37not available, the behavior depends on whether the device is in blocking 38or non-blocking mode. In the latter case, the call fails immediately 39with errno set to ``EWOULDBLOCK``. In the former case, the call blocks until 40an event becomes available. 41 42Return Value 43============ 44 45On success 0 is returned. 46 47On error -1 is returned, and the ``errno`` variable is set 48appropriately. 49 50.. flat-table:: 51 :header-rows: 0 52 :stub-columns: 0 53 54 - .. row 1 55 56 - ``EWOULDBLOCK`` 57 58 - There is no event pending, and the device is in non-blocking mode. 59 60 - .. row 2 61 62 - ``EOVERFLOW`` 63 64 - Overflow in event queue - one or more events were lost. 65 66Generic error codes are described at the 67:ref:`Generic Error Codes <gen-errors>` chapter. 68
