Darwin-kernel mailing list (Darwin-kernel@lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-kernel/site_archiver%40lists.a... I'm posting events from my KEXT to a user-land process using kev_msg_post() The doc states that this function returns EMSGSIZE if the message is too large. This is quite an issue for me, and the doc doesn't say anything about the max size. So can anyone tell me : - what is the exact maximum size of the message structure ? - if the max size depends on the kev_class or kev_subclass parameters of the message ? - if there's another function to use instead of kev_msg_post() to post larger messages to user-land (I might have to post messages as large as 1KB), or do I have to split my message into several pieces (in that case, can I be sure my user-land process will receive the messages in the exact post order ?) ?
