Thus leaving the + system in an inconsistent state. The question is how much effort you are + willing to spend on trying to make something atomic that really isn't. + + From the point of view of an application the main requirement is that + when you call VIDIOC_S_EXT_CTRLS and some values are invalid then an + error should be returned without actually affecting any controls. + + If all the values are correct, then it is acceptable to just give up + in case of low-level errors. + + It is important though that the application can tell when only a partial + configuration was done. The way we do that is through the error_idx field + of struct v4l2_ext_controls: if that is equal to the count field then no + controls were affected. Otherwise all controls before that index were + successful in performing their 'get' or 'set' operation, the control at + the given index failed, and you don't know what happened with the controls + after the failed one. Since if they were part of a control cluster they + could have been successfully processed (if a cluster member was encountered + at index < error_idx), they could have failed (if a cluster member was at + error_idx), or they may not have been processed yet (if the first cluster + member appeared after error_idx). + + It is all fairly theoretical, though. In practice all you can do is to + bail out. If error_idx == count, then it is an application bug. If + error_idx < count then it is only an application bug if the error code was + EBUSY. That usually means that something started streaming just when you + tried to set the controls.
