6.1.2.7.2. Synopsis¶

FE_GET_EVENT¶

int ioctl(int fd, FE_GET_EVENT, struct dvb_frontend_event *ev)

6.1.2.7.3. Arguments¶

fd: File descriptor returned by open().
ev: Points to the location where the event, if any, is to be stored.

6.1.2.7.4. Description¶

This ioctl call returns a frontend 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.

6.1.2.7.5. Return Value¶

On success 0 is returned.

On error -1 is returned, and the errno variable is set appropriately.

`EWOULDBLOCK`	There is no event pending, and the device is in non-blocking mode.
`EOVERFLOW`	Overflow in event queue - one or more events were lost.

Generic error codes are described at the Generic Error Codes chapter.
