Forgot to answer this one --- I think it's fair to assume the user knows the maximum size of the payload. What we also could do in such a case is to return the error (e.g. ENOSPC) and put the required size to the large event size field. But first someone must come up with a variable size event without well defined maximum size for this to make much sense. -- Kind regards, Sakari Ailus e-mail: sakari.ai...@iki.fi XMPP: sai...@retiisi.org.uk -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
