# HG changeset patch # User Ian Campbell <ian.campbell@xxxxxxxxxx> # Date 1330604774 0 # Node ID d36443bc098c28c2649f3e494ae6f44722870261 # Parent e5bc6847f24882143b71318e2683772f4f34251e libxl: make libxl_device_console internal consoles are not directly exposed to users of the library and there are no API functions for manipluating them (only the console_exec function). Rather than commit to a particular API now make the type internal. When a user does come along it is much easier to add a completely new API rather than to fix an existing broken one. It's easier to do this in a manner which users of the library can cope with in a compatible way e.g. adding a new API is easier to check for with ./configure.
