DMX_GET_EVENT

Name

DMX_GET_EVENT

Synopsis

Arguments

fd

File descriptor returned by :c:func:`open() <dvb-dmx-open>`.

ev

Pointer to the location where the event is to be stored.

Description

This ioctl call returns an event if available. If an event is not available, the behavior depends on whether the device is in blocking or non-blocking mode. In the latter case, the call fails immediately with errno set to EWOULDBLOCK. In the former case, the call blocks until an event becomes available.

Return Value

On success 0 is returned, on error -1 and the errno variable is set appropriately. The generic error codes are described at the :ref:`Generic Error Codes <gen-errors>` chapter.
